ADSP-TS101S
GENERAL DESCRIPTION
The ADSP-TS101S TigerSHARC processor is an ultrahigh performance, static superscalar processor optimized for large signal processing tasks and communications infrastructure. The DSP combines very wide memory widths with dual computation blocks--supporting 32- and 40-bit floating-point and 8-, 16-, 32-, and 64-bit fixed-point processing--to set a new standard of performance for digital signal processors. The TigerSHARC processor's static superscalar architecture lets the processor execute up to four instructions each cycle, performing 24 fixedpoint (16-bit) operations or six floating-point operations. Three independent 128-bit wide internal data buses, each connecting to one of the three 2M bit memory banks, enable quad word data, instruction, and I/O accesses and provide 14.4G bytes per second of internal memory bandwidth. Operating at 300 MHz, the ADSP-TS101S processor's core has a 3.3 ns instruction cycle time. Using its Single-Instruction, MultipleData (SIMD) features, the ADSP-TS101S can perform 2.4 billion 40-bit MACs or 600 million 80-bit MACs per second. Table 1 and Table 2 show the DSP's performance benchmarks. Table 1. General-Purpose Algorithm Benchmarks at 300 MHz

The ADSP-TS101S is code compatible with the other TigerSHARC processors. The Functional Block Diagram on Page 1 shows the ADSPTS101S processor's architectural blocks. These blocks include: * Dual compute blocks, each consisting of an ALU, multiplier, 64-bit shifter, and 32-word register file and associated data alignment buffers (DABs) * Dual integer ALUs (IALUs), each with its own 31-word register file for data addressing * A program sequencer with instruction alignment buffer (IAB), branch target buffer (BTB), and interrupt controller * Three 128-bit internal data buses, each connecting to one of three 2M bit memory banks * On-chip SRAM (6M bit) * An external port that provides the interface to host processors, multiprocessing space (DSPs), off-chip memory mapped peripherals, and external SRAM and SDRAM * A 14-channel DMA controller * Four link ports * Two 64-bit interval timers and timer expired pin * A 1149.1 IEEE compliant JTAG test access port for on-chip emulation Figure 2 shows a typical single processor system with external SDRAM. Figure 4 on Page 8 shows a typical multiprocessor system. The TigerSHARC processor uses a Static SuperscalarTM architecture. This architecture is superscalar in that the ADSP-TS101S processor's core can execute simultaneously from one to four 32-bit instructions encoded in a very large instruction word (VLIW) instruction line using the DSP's dual compute blocks. Because the DSP does not perform instruction reordering at run-time--the programmer selects which operations will execute in parallel prior to run-time--the order of instructions is static. With few exceptions, an instruction line, whether it contains one, two, three, or four 32-bit instructions, executes with a throughput of one cycle in an eight-deep processor pipeline. For optimal DSP program execution, programmers must follow the DSP's set of instruction parallelism rules when encoding an instruction line. In general, the selection of instructions that the DSP can execute in parallel each cycle depends on the instruction line resources each instruction requires and on the source and destination registers used in the instructions. The programmer has direct control of three core components--the IALUs, the compute blocks, and the program sequencer. The ADSP-TS101S, in most cases, has a two-cycle arithmetic execution pipeline that is fully interlocked, so whenever a computation result is unavailable for another operation dependent

DATA ALIGNMENT BUFFER (DAB)
The DAB is a quad word FIFO that enables loading of quad word data from nonaligned addresses. Normally, load instructions must be aligned to their data size so that quad words are loaded from a quad aligned address. Using the DAB significantly improves the efficiency of some applications, such as FIR filters.
on it, the DSP automatically inserts one or more stall cycles as needed. Efficient programming with dependency-free instructions can eliminate most computational and memory transfer data dependencies. In addition, the ADSP-TS101S supports SIMD operations two ways--SIMD compute blocks and SIMD computations.The programmer can direct both compute blocks to operate on the same data (broadcast distribution) or on different data (merged distribution). In addition, each compute block can execute four 16-bit or eight 8-bit SIMD computations in parallel.
DUAL INTEGER ALUS (IALUS)
The ADSP-TS101S has two IALUs that provide powerful address generation capabilities and perform many general-purpose integer operations. Each of the IALUs: * Provides memory addresses for data and update pointers * Supports circular buffering and bit-reverse addressing * Performs general-purpose integer operations, increasing programming flexibility * Includes a 31-word register file for each IALU As address generators, the IALUs perform immediate or indirect (pre- and post-modify) addressing. They perform modulus and bit-reverse operations with no constraints placed on memory addresses for the modulus data buffer placement. Each IALU can specify either a single, dual, or quad word access from memory. The IALUs have hardware support for circular buffers, bit reverse, and zero-overhead looping. Circular buffers facilitate efficient programming of delay lines and other data structures required in digital signal processing, and they are commonly

DUAL COMPUTE BLOCKS
The ADSP-TS101S has compute blocks that can execute computations either independently or together as a SIMD engine. The DSP can issue up to two compute instructions per compute block each cycle, instructing the ALU, multiplier, or shifter to perform independent, simultaneous operations. The compute blocks are referred to as X and Y in assembly syntax, and each block contains three computational units--an ALU, a multiplier, a 64-bit shifter--and a 32-word register file. * Register file--each compute block has a multiported 32-word, fully orthogonal register file used for transferring data between the computation units and data buses and for

used in digital filters and Fourier transforms. Each IALU provides registers for four circular buffers, so applications can set up a total of eight circular buffers. The IALUs handle address pointer wraparound automatically, reducing overhead, increasing performance, and simplifying implementation. Circular buffers can start and end at any memory location. Because the IALU's computational pipeline is one cycle deep, in most cases, integer results are available in the next cycle. Hardware (register dependency check) causes a stall if a result is unavailable in a given cycle.
Flexible Instruction Set
The 128-bit instruction line, which can contain up to four 32-bit instructions, accommodates a variety of parallel operations for concise programming. For example, one instruction line can direct the DSP to conditionally execute a multiply, an add, and a subtract in both computation blocks while it also branches to another location in the program. Some key features of the instruction set include: * Enhanced instructions for communications infrastructure to govern trellis decoding (for example, Viterbi and turbo decoders) and despreading via complex correlations * Algebraic assembly language syntax * Direct support for all DSP, imaging, and video arithmetic types, eliminating hardware modes * Branch prediction encoded in instruction, enables zerooverhead loops * Parallelism encoded in instruction line * Conditional execution optional for all instructions * User-defined, programmable partitioning between program and data memory
PROGRAM SEQUENCER
The ADSP-TS101S processor's program sequencer supports: * A fully interruptible programming model with flexible programming in assembly and C/C++ languages; handles hardware interrupts with high throughput and no aborted instruction cycles. * An eight-cycle instruction pipeline--three-cycle fetch pipe and five-cycle execution pipe--with computation results available two cycles after operands are available. * The supply of instruction fetch memory addresses; the sequencer's instruction alignment buffer (IAB) caches up to five fetched instruction lines waiting to execute; the program sequencer extracts an instruction line from the IAB and distributes it to the appropriate core component for execution. * The management of program structures and determination of program flow according to JUMP, CALL, RTI, RTS instructions, loop structures, conditions, interrupts, and software exceptions. * Branch prediction and a 128-entry branch target buffer (BTB) to reduce branch delays for efficient execution of conditional and unconditional branch instructions and zero-overhead looping; correctly predicted branches that are taken occur with zero-to-two overhead cycles, overcoming the three-to-six stage branch penalty. * Compact code without the requirement to align code in memory; the IAB handles alignment.
ON-CHIP SRAM MEMORY
The ADSP-TS101S has 6M bits of on-chip SRAM memory, divided into three blocks of 2M bits (64K words x 32 bits). Each block--M0, M1, and M2--can store program, data, or both, so applications can configure memory to suit specific needs. Placing program instructions and data in different memory blocks, however, enables the DSP to access data while performing an instruction fetch. The DSP's internal and external memory (Figure 3) is organized into a unified memory map, which defines the location (address) of all elements in the system. The memory map is divided into four memory areas--host space, external memory, multiprocessor space, and internal memory--and each memory space, except host memory, is subdivided into smaller memory spaces. Each internal memory block connects to one of the 128-bit wide internal buses--block M0 to bus MD0, block M1 to bus MD1, and block M2 to bus MD2--enabling the DSP to perform three memory transfers in the same cycle. The DSP's internal bus architecture provides a total memory bandwidth of 14.4G bytes per second, enabling the core and I/O to access eight 32-bit data words (256 bits) and four 32-bit instructions each cycle. The DSP's flexible memory structure enables: * DSP core and I/O access of different memory blocks in the same cycle * DSP core access of all three memory blocks in parallel-- one instruction and two data accesses * Programmable partitioning of program and data memory * Program access of all memory as 32-, 64-, or 128-bit words--16-bit words with the DAB * Complete context switch in less than 20 cycles (66 ns)
Interrupt Controller
The DSP supports nested and non-nested interrupts. Each interrupt type has a register in the interrupt vector table. Also, each has a bit in both the interrupt latch register and the interrupt mask register. All interrupts are fixed as either level sensitive or edge sensitive, except the IRQ3-0 hardware interrupts, which are programmable. The DSP distinguishes between hardware interrupts and software exceptions, handling them differently. When a software exception occurs, the DSP aborts all other instructions in the instruction pipe. When a hardware interrupt occurs, the DSP continues to execute instructions already in the instruction pipe.

EXTERNAL PORT (OFF-CHIP MEMORY/PERIPHERALS INTERFACE)
The ADSP-TS101S processor's external port provides the processor's interface to off-chip memory and peripherals. The 4G word address space is included in the DSP's unified address space. The separate on-chip buses--three 128-bit data buses and three 32-bit address buses--are multiplexed at the external port to create an external system bus with a single 64-bit data bus and a single 32-bit address bus. The external port supports data transfer rates of 800M bytes per second over external bus. The external bus can be configured for 32- or 64-bit operation. When the system bus is configured for 64-bit operation, the lower 32 bits of the external data bus connect to even addresses, and the upper 32 bits connect to odd addresses. The external port supports pipelined, slow, and SDRAM protocols. Addressing of external memory devices and memory mapped peripherals is facilitated by on-chip decoding of high order address lines to generate memory bank select signals. The ADSP-TS101S provides programmable memory, pipeline depth, and idle cycle for synchronous accesses, and external acknowledge controls to support interfacing to pipelined or slow devices, host processors, and other memory-mapped peripherals with variable access, hold, and disable time requirements.
Host Interface
The ADSP-TS101S provides an easy and configurable interface between its external bus and host processors through the external port. To accommodate a variety of host processors, the host

ADSP-TS101S
interface supports pipelined or slow protocols for accesses of the host as slave. Each protocol has programmable transmission parameters, such as idle cycles, pipe depth, and internal wait cycles. The host interface supports burst transactions initiated by a host processor. After the host issues the starting address of the burst and asserts the BRST signal, the DSP increments the address internally while the host continues to assert BRST. The host interface provides a deadlock recovery mechanism that enables a host to recover from deadlock situations involving the DSP. The BOFF signal provides the deadlock recovery mechanism. When the host asserts BOFF, the DSP backs off the current transaction and asserts HBG and relinquishes the external bus. The host can directly read or write the internal memory of the ADSP-TS101S, and it can access most of the DSP registers, including DMA control (TCB) registers. Vector interrupts support efficient execution of host commands.
EPROM Interface
The ADSP-TS101S can be configured to boot from external 8-bit EPROM at reset through the external port. An automatic process (which follows reset) loads a program from the EPROM into internal memory. This process uses 16 wait cycles for each read access. During booting, the BMS pin functions as the EPROM chip select signal. The EPROM boot procedure uses DMA Channel 0, which packs the bytes into 32-bit instructions. Applications can also access the EPROM (write flash memories) during normal operation through DMA. The EPROM or flash memory interface is not mapped in the DSP's unified memory map. It is a byte address space limited to a maximum of 16M bytes (24 address bits). The EPROM or flash memory interface can be used after boot via a DMA.
DMA CONTROLLER
The ADSP-TS101S processor's on-chip DMA controller, with 14 DMA channels, provides zero-overhead data transfers without processor intervention. The DMA controller operates independently and invisibly to the DSP's core, enabling DMA operations to occur while the DSP's core continues to execute program instructions. The DMA controller performs DMA transfers between: * Internal memory and external memory and memorymapped peripherals * Internal memory of other DSPs on a common bus, a host processor, or link port I/O * External memory and external peripherals or link port I/O * External bus master and internal memory or link port I/O The DMA controller provides a number of additional features. The DMA controller supports flyby transfers. Flyby operations only occur through the external port (DMA Channel 0) and do not involve the DSP's core. The DMA controller acts as a conduit to transfer data from one external device to another through external memory. During a transaction, the DSP: * Relinquishes the external data bus * Outputs addresses, memory selects (MS1-0, MSSD, RAS, CAS, and SDWE) and the FLYBY, IOEN, and RD/WR strobes * Responds to ACK DMA chaining is also supported by the DMA controller. DMA chaining operations enable applications to automatically link one DMA transfer sequence to another for continuous transmission. The sequences can occur over different DMA channels and have different transmission attributes. The DMA controller also supports two-dimensional transfers. The DMA controller can access and transfer two-dimensional memory arrays on any DMA transmit or receive channel. These transfers are implemented with index, count, and modify registers for both the X and Y dimensions.
Multiprocessor Interface
The ADSP-TS101S offers powerful features tailored to multiprocessing DSP systems through the external port and link ports. This multiprocessing capability provides highest bandwidth for interprocessor communication, including: * Up to eight DSPs on a common bus * On-chip arbitration for glueless multiprocessing * Link ports for point-to-point communication The external port and link ports provide integrated, glueless multiprocessing support. The external port supports a unified address space (see Figure 3) that enables direct interprocessor accesses of each ADSPTS101S processor's internal memory and registers. The DSP's on-chip distributed bus arbitration logic provides simple, glueless connection for systems containing up to eight ADSPTS101S processors and a host processor. Bus arbitration has a rotating priority. Bus lock supports indivisible read-modifywrite sequences for semaphores. A bus fairness feature prevents one DSP from holding the external bus too long. The DSP's four link ports provide a second path for interprocessor communications with throughput of 1G bytes per second. The cluster bus provides 800M bytes per second throughput-- with a total of 1.8G bytes per second interprocessor bandwidth.
SDRAM Controller
The SDRAM controller controls the ADSP-TS101S processor's transfers of data to and from synchronous DRAM (SDRAM). The throughput is 32 or 64 bits per SCLK cycle using the external port and SDRAM control pins. The SDRAM interface provides a glueless interface with standard SDRAMs--16M bit, 64M bit, 128M bit, and 256M bit. The DSP directly supports a maximum of 64M words x 32 bits of SDRAM. The SDRAM interface is mapped in external memory in the DSP's unified memory map.

Figure 4. Shared Memory Multiprocessing System
The DMA controller performs the following DMA operations: * External port block transfers. Four dedicated bidirectional DMA channels transfer blocks of data between the DSP's internal memory and any external memory or memorymapped peripheral on the external bus. These transfers support master mode and handshake mode protocols. * Link port transfers. Eight dedicated DMA channels (four transmit and four receive) transfer quad word data only between link ports and between a link port and internal or
external memory. These transfers only use handshake mode protocol. DMA priority rotates between the four receive channels. * AutoDMA transfers. Two dedicated unidirectional DMA channels transfer data received from an external bus master to internal memory or to link port I/O. These transfers only use slave mode protocol, and an external bus master must initiate the transfer.
LINK PORTS
The DSP's four link ports provide additional 8-bit bidirectional I/O capability. With the ability to operate at a double data rate-- latching data on both the rising and falling edges of the clock--

running at 125 MHz, each link port can support up to 250M bytes per second, for a combined maximum throughput of 1G bytes per second. The link ports provide an optional communications channel that is useful in multiprocessor systems for implementing point to point interprocessor communications. Applications can also use the link ports for booting. Each link port has its own double-buffered input and output registers. The DSP's core can write directly to a link port's transmit register and read from a receive register, or the DMA controller can perform DMA transfers through eight (four transmit and four receive) dedicated link port DMA channels. Each link port has three signals that control its operation. LxCLKOUT and LxCLKIN implement clock/acknowledge handshaking. LxDIR indicates the direction of transfer and is used only when buffering the LxDAT signals. An example application would be using differential low-swing buffers for long twisted-pair wires. LxDAT provides the 8-bit data bus input/output. Applications can program separate error detection mechanisms for transmit and receive operations (applications can use the checksum mechanism to implement consecutive link port transfers), the size of data packets, and the speed at which bytes are transmitted. Under certain conditions, the link port receiver can initiate a token switch to reverse the direction of transfer; the transmitter becomes the receiver and vice versa. After reset, the ADSP-TS101S has four boot options for beginning operation: * Boot from EPROM. The DSP defaults to EPROM booting when the BMS pin strap option is set low. See Strap Pin Function Descriptions on Page 19. * Boot by an external master (host or another ADSPTS101S). Any master on the cluster bus can boot the ADSP-TS101S through writes to its internal memory or through autoDMA. * Boot by link port. All four receive link DMA channels are initialized after reset to transfer a 256-word block to internal memory address 0 to 255, and to issue an interrupt at the end of the block (similar to EP DMA). The corresponding DMA interrupts are set to address zero (0). * No boot--Start running from an external memory. Using the "no boot" option, the ADSP-TS101S must start running from an external memory, caused by asserting one of the IRQ3-0 interrupt signals. The ADSP-TS101S core always exits from reset in the idle state and waits for an interrupt. Some of the interrupts in the interrupt vector table are initialized and enabled after reset.
LOW POWER OPERATION
The ADSP-TS101S can enter a low power sleep mode in which its core does not execute instructions, reducing power consumption to a minimum. The ADSP-TS101S exits sleep mode when it senses a falling edge on any of its IRQ3-0 interrupt inputs. The interrupt, if enabled, causes the ADSP-TS101S to execute the corresponding interrupt service routine. This feature is useful for systems that require a low power standby mode.
TIMER AND GENERAL-PURPOSE I/O
The ADSP-TS101S has a timer pin (TMR0E) that generates output when a programmed timer counter has expired. Also, the DSP has four programmable general-purpose I/O pins (FLAG3-0) that can function as either single bit input or output. As outputs, these pins can signal peripheral devices; as inputs, they can provide the test for conditional branching.
CLOCK DOMAINS
As shown in Figure 5, the ADSP-TS101S has two clock inputs, SCLK (system clock) and LCLK (local clock).
EXTERNAL INTERFACE CCLK (INSTRUCTION RATE) /LR DLL LxCLKOUT/LxCLKIN (LINK PORT RATE)
RESET AND BOOTING
The ADSP-TS101S has two levels of reset (see reset specifications on Page 24): * Power-up reset--after power-up of the system, and strap options are stable, the RESET pin must be asserted (low). * Normal reset--for any resets following the power-up reset sequence, the RESET pin must be asserted. The DSP can be reset internally (core reset) by setting the SWRST bit in SQCTL. The core is reset, but not the external port or I/O.

These inputs drive its two major clock domains: * SCLK (system clock). Provides clock input for the external bus interface and defines the ac specification reference for the external bus signals. The external bus interface runs at 1x the SCLK frequency. A DLL locks internal SCLK to SCLK input. * LCLK (local clock). Provides clock input to the internal clock driver, CCLK, which is the internal clock for the core, internal buses, memory, and link ports. The instruction

execution rate is equal to CCLK. A PLL from LCLK generates CCLK which is phase-locked. The LCLKRAT pins define the clock multiplication of LCLK to CCLK (see Table 4). The link port clock is generated from CCLK via a software programmable divisor. RESET must be asserted until LCLK is stable and within specification for at least 2 ms. This applies to power-up as well as any dynamic modification of LCLK after power-up. Dynamic modification may include LCLK going out of specification as long as RESET is asserted. Connecting SCLK and LCLK to the same clock source is a requirement for the device. Using an integer clock multiplication value provides predictable cycle-by-cycle operation, a requirement of fault-tolerant systems and some multiprocessing systems. Noninteger values are completely functional and acceptable for applications that do not require predictable cycle-by-cycle operation. The required power-on sequence for the DSP is to provide VDD (and VDD_A) before VDD_IO.
FILTERING REFERENCE VOLTAGE AND CLOCKS
Figure 6 shows a possible circuit for filtering VREF, SCLK_N, and LCLK_N. This circuit provides the reference voltage for the switching voltage, system clock, and local clock references.

OUTPUT PIN DRIVE STRENGTH CONTROL
Pins CONTROLIMP2-0 and DS2-0 work together to control the output drive strength of two groups of pins, the Address/Data/Control pin group and the Link pin group. CONTROLIMP2-0 independently configures the two pin groups to the maximum drive strength or to a digitally controlled drive strength that is selectable by the DS2-0 pins (see Table 13 on Page 18). If the digitally controlled drive strength is selected for a pin group, the DS2-0 pins determine one of eight strength levels for that group (see Table 14 on Page 18). The drive strength selected varies the slew rate of the driver. Drive strength 0 (DS2-0 = 000) is the weakest and slowest slew rate. Drive strength 7 (DS2-0 = 111) is the strongest and fastest slew rate. The stronger drive strengths are useful for high frequency switching while the lower strengths may allow use of a relaxed design methodology. The strongest drive strengths have a larger di/dt and thus require more attention to signal integrity issues such a ringing, reflections and coupling. Also a larger di/dt can increase external supply rail noise, which impacts power supply and power distribution design. The drive strengths for the EMU, CPA, and DPA pins are not controllable and are fixed to the maximum level. For drive strength calculation, see Output Drive Currents on Page 32.

DEVELOPMENT TOOLS
The ADSP-TS101S is supported with a complete set of CROSSCORE(R) software and hardware development tools, including Analog Devices emulators and VisualDSP++(R) development environment. The same emulator hardware that supports other TigerSHARC processors also fully emulates the ADSP-TS101S. The VisualDSP++ project management environment lets programmers develop and debug an application. This environment includes an easy to use assembler (which is based on an algebraic syntax), an archiver (librarian/library builder), a linker, a loader, a cycle-accurate instruction-level simulator, a C/C++ compiler, and a C/C++ run-time library that includes DSP and mathematical functions. A key point for these tools is C/C++ code efficiency. The compiler has been developed for efficient translation of C/C++ code to DSP assembly. The DSP has architectural features that improve the efficiency of compiled C/C++ code. The VisualDSP++ debugger has a number of important features. Data visualization is enhanced by a plotting package that offers a significant level of flexibility. This graphical representation of user data enables the programmer to quickly determine the performance of an algorithm. As algorithms grow in complexity, this capability can have increasing significance on the designer's development schedule, increasing productivity. Statistical profiling enables the programmer to nonintrusively poll the processor as it is running the program. This feature, unique to VisualDSP++, enables the software developer to passively gather important code execution metrics without interrupting the real-time characteristics of the program. Essentially, the developer can identify bottlenecks in software quickly and
POWER SUPPLIES
The ADSP-TS101S has separate power supply connections for internal logic (VDD), analog circuits (VDD_A), and I/O buffer (VDD_IO) power supply. The internal (VDD) and analog (VDD_A) supplies must meet the 1.2 V requirement. The I/O buffer (VDD_IO) supply must meet the 3.3 V requirement. The analog supply (VDD_A) powers the clock generator PLLs. To produce a stable clock, systems must provide a clean power supply to power input VDD_A. Designs must pay critical attention to bypassing the VDD_A supply.

efficiently. By using the profiler, the programmer can focus on those areas in the program that impact performance and take corrective action. Debugging both C/C++ and assembly programs with the VisualDSP++ debugger, programmers can: * View mixed C/C++ and assembly code (interleaved source and object information) * Insert breakpoints * Set conditional breakpoints on registers, memory, and stacks * Trace instruction execution * Perform linear or statistical profiling of program execution * Fill, dump, and graphically plot the contents of memory * Perform source level debugging * Create custom debugger windows The VisualDSP++ IDDE lets programmers define and manage DSP software development. Its dialog boxes and property pages let programmers configure and manage all of the TigerSHARC development tools, including the color syntax highlighting in the VisualDSP++ editor. This capability permits programmers to: * Control how the development tools process inputs and generate outputs * Maintain a one-to-one correspondence with the tool's command line switches The VisualDSP++ Kernel (VDK) incorporates scheduling and resource management tailored specifically to address the memory and timing constraints of DSP programming. These capabilities enable engineers to develop code more effectively, eliminating the need to start from the very beginning, when developing new application code. The VDK features include threads, critical and unscheduled regions, semaphores, events, and device flags. The VDK also supports priority-based, preemptive, cooperative, and time-sliced scheduling approaches. In addition, the VDK was designed to be scalable. If the application does not use a specific feature, the support code for that feature is excluded from the target system. Because the VDK is a library, a developer can decide whether to use it or not. The VDK is integrated into the VisualDSP++ development environment, but can also be used via standard command line tools. When the VDK is used, the development environment assists the developer with many error-prone tasks and assists in managing system resources, automating the generation of various VDK-based objects, and visualizing the system state, when debugging an application that uses the VDK. VCSE is Analog Devices technology for creating, using, and reusing software components (independent modules of substantial functionality) to quickly and reliably assemble software applications. It is also used for downloading components from the Web, dropping them into the application, and publishing component archives from within VisualDSP++. VCSE supports component implementation in C/C++ or assembly language. Use the expert linker to visually manipulate the placement of code and data on the embedded system. View memory utilization in a color-coded graphical form, easily move code and data to different areas of the DSP or external memory with a drag of the mouse, examine run-time stack and heap usage. The expert linker is fully compatible with existing linker definition file (LDF), allowing the developer to move between the graphical and textual environments. Analog Devices DSP emulators use the IEEE 1149.1 JTAG Test Access Port of the ADSP-TS101S processor to monitor and control the target board processor during emulation. The emulator provides full speed emulation, allowing inspection and modification of memory, registers, and processor stacks. Nonintrusive in-circuit emulation is assured by the use of the processor's JTAG interface--the emulator does not affect target system loading or timing. In addition to the software and hardware development tools available from Analog Devices, third parties provide a wide range of tools supporting the TigerSHARC processor family. Hardware tools include TigerSHARC processor PC plug-in cards. Third party software tools include DSP libraries, realtime operating systems, and block diagram design tools.
DESIGNING AN EMULATORCOMPATIBLE DSP BOARD (TARGET)
The Analog Devices family of emulators are tools that every DSP developer needs to test and debug hardware and software systems. Analog Devices has supplied an IEEE 1149.1 JTAG test access port (TAP) on each JTAG DSP. The emulator uses the TAP to access the internal features of the DSP, allowing the developer to load code, set breakpoints, observe variables, observe memory, and examine registers. The DSP must be halted to send data and commands, but once an operation has been completed by the emulator, the DSP system is set running at full speed with no impact on system timing. To use these emulators, the target board must include a header that connects the DSP's JTAG port to the emulator. For details on target board design issues including mechanical layout, single processor connections, multiprocessor scan chains, signal buffering, signal termination, and emulator pod logic, see the EE-68: Analog Devices JTAG Emulation Technical Reference on the Analog Devices website (www.analog.com)-- use site search on "EE-68." This document is updated regularly to keep pace with improvements to emulator support.

PIN FUNCTION DESCRIPTIONS
While most of the ADSP-TS101S processor's input pins are normally synchronous--tied to a specific clock--a few are asynchronous. For these asynchronous signals, an on-chip synchronization circuit prevents metastability problems. The synchronous ac specification for asynchronous signals is used only when predictable cycle-by-cycle behavior is required. All inputs are sampled by a clock reference, therefore input specifications (asynchronous minimum pulse widths or synchronous input setup and hold) must be met to guarantee recognition.
PIN STATES AT RESET
The output pins can be three-stated during normal operation. The DSP three-states all outputs during reset, allowing these pins to get to their internal pull-up or pull-down state. Some output pins (control signals) have a pull-up or pull-down that maintains a known value during transitions between different drivers.
PIN DEFINITIONS
The Type column in the following pin definitions tables describes the pin type, when the pin is used in the system. The Term (for termination) column describes the pin termination type if the pin is not used by the system. Note that some pins are always used (indicated with au symbol).

The DSP's core clock (instruction cycle rate) = n x LCLK, where n is user-programmable to 2, 2.5, 3, 3.5, 4, 5, or 6 as shown in Table 4. These pins must have a constant value while the DSP is powered. SCLK_N I au System Clock Reference. Connect this pin to VREF as shown in Figure 6. SCLK_P I au System Clock Input. The DSP's system input clock for cluster bus. This pin must be connected to the same clock source as LCLK_P. For more information, see Clock Domains on Page 9. SCLKFREQ3 I (pu2) au SCLK Frequency. SCLKFREQ = 1 is required. The SCLKFREQ pin must have a constant value while the DSP is powered. RESET I/A au Reset. Sets the DSP to a known state and causes program to be in idle state.

ADSP-TS101S
Table 5. Pin Definitions--External Port Bus Controls
Description Address Bus. The DSP issues addresses for accessing memory and peripherals on these pins. In a multiprocessor system, the bus master drives addresses for accessing internal memory or I/O processor registers of other ADSP-TS101S processors. The DSP inputs addresses when a host or another DSP accesses its internal memory or I/O processor registers. DATA63-01 I/O/T nc External Data Bus. Data and instructions are received, and driven by the DSP, on these pins. RD2 I/O/T (pu3) nc Memory Read. RD is asserted whenever the DSP reads from any slave in the system, excluding SDRAM. When the DSP is a slave, RD is an input and indicates read transactions that access its internal memory or universal registers. In a multiprocessor system, the bus master drives RD. The RD pin changes concurrently with ADDR pins. I/O/T (pu3) nc Write Low. WRL is asserted in two cases: When the ADSP-TS101S writes to an even address word WRL2 of external memory or to another external bus agent; and when the ADSP-TS101S writes to a 32-bit zone (host, memory, or DSP programmed to 32-bit bus). An external master (host or DSP) asserts WRL for writing to a DSP's low word of internal memory. In a multiprocessor system, the bus master drives WRL. The WRL pin changes concurrently with ADDR pins. When the DSP is a slave, WRL is an input and indicates write transactions that access its internal memory or universal registers. 2 3 WRH I/O/T (pu ) nc Write High. WRH is asserted when the ADSP-TS101S writes a long word (64 bits) or writes to an odd address word of external memory or to another external bus agent on a 64-bit data bus. An external master (host or another DSP) must assert WRH for writing to a DSP's high word of 64-bit data bus. In a multiprocessing system, the bus master drives WRH. The WRH pin changes concurrently with ADDR pins. When the DSP is a slave, WRH is an input and indicates write transactions that access its internal memory or universal registers. ACK I/O/T epu Acknowledge. External slave devices can deassert ACK to add wait states to external memory accesses. ACK is used by I/O devices, memory controllers, and other peripherals on the data phase. The DSP can deassert ACK to add wait states to read accesses of its internal memory. The ADSP-TS101S does not drive ACK during slave writes. Therefore, an external (approximately 10 k) pull-up is required. BMS2, 4 O/T au Boot Memory Select. BMS is the chip select for boot EPROM or flash memory. During reset, the (pu/pd3) DSP uses BMS as a strap pin (EBOOT) for EPROM boot mode. When the DSP is configured to boot from EPROM, BMS is active during the boot sequence. Pull-down enabled during RESET (asserted); pull-up enabled after RESET (deasserted). In a multiprocessor system, the DSP bus master drives BMS. For details see Reset and Booting on Page 9 and the EBOOT signal description in Table 16 on Page 19. O/T (pu3) nc Memory Select. MS0 or MS1 is asserted whenever the DSP accesses memory banks 0 or 1, MS1-02 respectively. MS1-0 are decoded memory address pins that change concurrently with ADDR pins. When ADDR31:26 = 0b000010, MS0 is asserted. When ADDR31:26 = 0b000011, MS1 is asserted. In multiprocessor systems, the master DSP drives MS1-0. Type column symbols: A = asynchronous; G = ground; I = input; O = output; o/d = open drain output; P = power supply; pd = internal pull-down approximately 100 k; pu = internal pull-up approximately 100 k; T = three-state Term (for termination) column symbols: epd = external pull-down approximately 10 k to VSS; epu = external pull-up approximately 10 k to VDD-IO, nc = not connected; au = always used.

Description Memory Select Host. MSH is asserted whenever the DSP accesses the host address space (ADDR31:28 0b0000). MSH is a decoded memory address pin that changes concurrently with ADDR pins. In a multiprocessor system, the bus master DSP drives MSH. BRST2 I/O/T (pu3) nc Burst. The current bus master (DSP or host) asserts this pin to indicate that it is reading or writing data associated with consecutive addresses. A slave device can ignore addresses after the first one and increment an internal address counter after each transfer. For host-to-DSP burst accesses, the DSP increments the address automatically while BRST is asserted. Type column symbols: A = asynchronous; G = ground; I = input; O = output; o/d = open drain output; P = power supply; pd = internal pull-down approximately 100 k; pu = internal pull-up approximately 100 k; T = three-state Term (for termination) column symbols: epd = external pull-down approximately 10 k to VSS; epu = external pull-up approximately 10 k to VDD-IO, nc = not connected; au = always used.

Term nc
The address and data buses may float for several cycles during bus mastership transitions between a TigerSHARC processor and a host. Floating in this case means that these inputs are not driven by any source and that dc-biased terminations are not present. It is not necessary to add pull-ups as there are no reliability issues and the worst-case power consumption for these floating inputs is negligible. Unconnected address pins may require pull-ups or pull-downs to avoid erroneous slave accesses, depending on the system. Unconnected data pins may be left floating. 2 The internal pull-up may not be sufficient. A stronger pull-up may be necessary. 3 See Electrical Characteristics on Page 20 for maximum and minimum current consumption for pull-up and pull-down resistances. 4 The internal pull-down may not be sufficient. A stronger pull-down may be necessary.
Table 6. Pin Definitions--External Port Arbitration
Description Multiprocessing Bus Request Pins. Used by the DSPs in a multiprocessor system to arbitrate for bus mastership. Each DSP drives its own BRx line (corresponding to the value of its ID2-0 inputs) and monitors all others. In systems with fewer than eight DSPs, set the unused BRx pins high. ID2-01 I (pd2) au Multiprocessor ID. Indicates the DSP's ID. From the ID, the DSP determines its order in a multiprocessor system. These pins also indicate to the DSP which bus request (BR0-BR7) to assert when requesting the bus: 000 = BR0, 001 = BR1, 010 = BR2, 011 = BR3, 100 = BR4, 101 = BR5, 110 = BR6, or 111 = BR7. ID2-0 must have a constant value during system operation and can change during reset only. 1 2 BM O (pd ) au Bus Master. The current bus master DSP asserts BM. For debugging only. At reset this is a strap pin. For more information, see Table 16 on Page 19. BOFF I epu Back Off. A deadlock situation can occur when the host and a DSP try to read from each other's bus at the same time. When deadlock occurs, the host can assert BOFF to force the DSP to relinquish the bus before completing its outstanding transaction, but only if the outstanding transaction is to host memory space (MSH). BUSLOCK3 O/T (pu2) nc Bus Lock Indication. Provides an indication that the current bus master has locked the bus. HBR I epu Host Bus Request. A host must assert HBR to request control of the DSP's external bus. When HBR is asserted in a multiprocessing system, the bus master relinquishes the bus and asserts HBG once the outstanding transaction is finished. Type column symbols: A = asynchronous; G = ground; I = input; O = output; o/d = open drain output; P = power supply; pd = internal pull-down approximately 100 k; pu = internal pull-up approximately 100 k; T = three-state Term (for termination) column symbols: epd = external pull-down approximately 10 k to VSS; epu = external pull-up approximately 10 k to VDD-IO, nc = not connected; au = always used.

Description Host Bus Grant. Acknowledges HBR and indicates that the host can take control of the external bus. When relinquishing the bus, the master DSP three-states the ADDR31-0, DATA63-0, MSH, MSSD, MS1-0, RD, WRL, WRH, BMS, BRST, FLYBY, IOEN, RAS, CAS, SDWE, SDA10, SDCKE, LDQM and HDQM pins, and the DSP puts the SDRAM in self-refresh mode. The DSP asserts HBG until the host deasserts HBR. In multiprocessor systems, the current bus master DSP drives HBG, and all slave DSPs monitor HBG. I/O (o/d) See Core Priority Access. Asserted while the DSP's core accesses external memory. This pin enables CPA next a slave DSP to interrupt a master DSP's background DMA transfers and gain control of the column external bus for core-initiated transactions. CPA is an open drain output, connected to all DSPs in the system. The CPA pin has an internal 500 pull-up resistor, which is only enabled on the DSP with ID2-0 = 0. If ID0 is not used, terminate this pin as either epu or nc. If ID7-1 is not used, terminate this pin as epu. DPA I/O (o/d) See DMA Priority Access. Asserted while a high priority DSP DMA channel accesses external next memory. This pin enables a high priority DMA channel on a slave DSP to interrupt transfers of column a normal priority DMA channel on a master DSP and gain control of the external bus for DMAinitiated transactions. DPA is an open drain output, connected to all DSPs in the system. The DPA pin has an internal 500 pull-up resistor, which is only enabled on the DSP with ID2-0 = 0. If ID0 is not used, terminate this pin as either epu or nc. If ID7-1 is not used, terminate this pin as epu. Type column symbols: A = asynchronous; G = ground; I = input; O = output; o/d = open drain output; P = power supply; pd = internal pull-down approximately 100 k; pu = internal pull-up approximately 100 k; T = three-state Term (for termination) column symbols: epd = external pull-down approximately 10 k to VSS; epu = external pull-up approximately 10 k to VDD-IO, nc = not connected; au = always used.

Description Memory Select SDRAM. MSSD is asserted whenever the DSP accesses SDRAM memory space. MSSD is a decoded memory address pin that is asserted whenever the DSP issues an SDRAM command cycle (access to ADDR31:26 = 0b000001). MSSD in a multiprocessor system is driven by the master DSP. RAS1 I/O/T (pu2) nc Row Address Select. When sampled low, RAS indicates that a row address is valid in a read or write of SDRAM. In other SDRAM accesses, RAS defines the type of operation to execute according to SDRAM specification. CAS1 I/O/T (pu2) nc Column Address Select. When sampled low, CAS indicates that a column address is valid in a read or write of SDRAM. In other SDRAM accesses, CAS defines the type of operation to execute according to the SDRAM specification. 1 2 LDQM O/T (pu ) nc Low Word SDRAM Data Mask. When LDQM is sampled high, the DSP three-states the SDRAM DQ buffers. LDQM is valid on SDRAM transactions when CAS is asserted and is inactive on read transactions. On write transactions, LDQM is active when accessing an odd address word on a 64-bit memory bus to disable the write of the low word. HDQM1 O/T (pu2) nc High Word SDRAM Data Mask. When HDQM is sampled high, the DSP three-states the SDRAM DQ buffers. HDQM is valid on SDRAM transactions when CAS is asserted and is inactive on read transactions. On write transactions, HDQM is active when accessing an even address in word accesses or is active when memory is configured for a 32-bit bus to disable the write of the high word. 1 2 SDA10 O/T (pu ) nc SDRAM Address bit 10 pin. Separate A10 signals enable SDRAM refresh operation while the DSP executes non-SDRAM transactions. 1, 3 SDCKE I/O/T nc SDRAM Clock Enable. Activates the SDRAM clock for SDRAM self-refresh or suspend modes. A (pu/pd2) slave DSP in a multiprocessor system does not have the pull-up or pull-down. A master DSP (or ID = 0 in a single processor system) has a 100 k pull-up before granting the bus to the host, except when the SDRAM is put in self-refresh mode. In self-refresh mode, the master has a 100 k pull-down before granting the bus to the host. SDWE1 I/O/T (pu2) nc SDRAM Write Enable.

The link port data pins, if connected or floated for extended periods (for example, token slave with no token master), do not require pull-ups or pull-downs as there are no reliability issues and the worst-case power consumption for these floating inputs is negligible. Floating in this case means that these inputs are not driven by any source and that dc-biased terminations are not present. 2 The internal pull-down may not be sufficient.

VREF can be connected to a power supply or set by a voltage divider circuit. The voltage divider should have an HF decoupling capacitor (1 nF HF SMD) connected to VSS. Tie the decoupling capacitor between VREF input and VSS, as close to the DSP's pins as possible. For more information, see Filtering Reference Voltage and Clocks on Page 10. VSS G au Ground pins.

STRAP PIN FUNCTION DESCRIPTIONS
Some pins have alternate functions at reset. Strap options set DSP operating modes. During reset, the DSP samples the strap option pins. Strap pins have an approximately 100 k pulldown for the default value. If a strap pin is not connected to an external pull-up or logic load, the DSP samples the default value during reset. If strap pins are connected to logic inputs, a stronger external pull-down may be required to ensure default value Table 16. Pin Definitions--I/O Strap Pins

depending on leakage and/or low level input current of the logic load. To set a mode other than the default mode, connect the strap pin to a sufficiently stronger external pull-up. In a multiprocessor system, up to eight DSPs may be connected on the cluster bus, resulting in parallel combination of strap pin pulldown resistors.

Stresses greater than those listed above may cause permanent damage to the device. These are stress ratings only; functional operation of the device at these or any other conditions greater than those indicated in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
ESD SENSITIVITY
CAUTION ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on the human body and test equipment and can discharge without detection. Although the ADSP-TS101S features proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high-energy electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance degradation or loss of functionality.
TIMING SPECIFICATIONS
With the exception of link port, IRQ3-0, DMAR3-0, TMR0E, FLAG3-0 (input), and TRST pins, all ac timing for the ADSPTS101S is relative to a reference clock edge. Because input setup/hold, output valid/hold, and output enable/disable times are relative to a clock edge, the timing data for the ADSPTS101S has few calculated (formula-based) values. For information on ac timing, see General AC Timing. For information on link port transfer timing, see Link Ports Data Transfer and Token Switch Timing on Page 29.
General AC Timing
Timing is measured on signals when they cross the 1.5 V level as described in Figure 15 on Page 28. All delays (in nanoseconds) are measured between the point that the first signal reaches 1.5 V and the point that the second signal reaches 1.5 V. The ac asynchronous timing data for the IRQ3-0, DMAR3-0, TMR0E, FLAG3-0 (input), and TRST pins appears in Table 17. The general ac timing data appears in Table 17, Table 25, and Table 26. All ac specifications are measured with the load specified in Figure 7, and with the output drive strength set to strength 4. Output valid and hold are based on standard capacitive loads: 30 pF on all pins. The delay and hold specifications given should be derated by a drive strength related factor for loads other than the nominal value of 30 pF. In order to calculate the output valid and hold times for different load conditions and/or output drive strengths, refer to Figure 31 on Page 34 through Figure 38 on Page 36 (Rise and Fall Time vs. Load Capacitance) and Figure 39 on Page 36 (Output Valid vs. Load Capacitance and Drive Strength).

The output valid (max) value in this column applies for the standard 30 pF capacitive load used in testing. To see how output valid varies with capacitive loading, see Figure 39 on Page 36. 2 The external port protocols employ bus IDLE cycles for bus mastership transitions as well as slave address boundary crossings to avoid any potential bus contention.

TEST CONDITIONS
The test conditions for timing parameters appearing in Table 25 on Page 25 and Table 26 on Page 27 include output disable time, output enable time, and capacitive loading. The timing specifications for the DSP apply for the voltage reference levels in Figure 28. t C V L = -------------RAMP I D
INPUT OR OUTPUT
1.5V
1.5V
The output enable time tENA is the difference between tMEASURED_ENA and tRAMP as shown in Figure 29. The time tMEASURED_ENA is the interval from when the reference signal switches to when the output voltage ramps V from the measured three-stated output level. The tRAMP value is calculated with test load CL, drive current ID, and with V equal to 0.5 V.

Figure 30 shows the circuit with variable capacitance that is used for measuring typical output rise and fall times. Figure 31 through Figure 38 show how output rise time varies with capacitance. Figure 39 graphically shows how output valid varies with load capacitance. (Note that this graph or derating does not apply to output disable delays; see Output Disable Time on Page 34.) The graphs of Figure 31 through Figure 39 may not be linear outside the ranges shown.

Output Disable Time
Output pins are considered to be disabled when they stop driving, go into a high impedance state, and start to decay from their output high or low voltage. The time for the voltage on the bus to decay by V is dependent on the capacitive load, CL and the load current, IL. This decay time can be approximated by the following equation: C L V t DECAY = -------------IL The output disable time tDIS is the difference between tMEASURED_DIS and tDECAY as shown in Figure 29. The time tMEASURED_DIS is the interval from when the reference signal switches to when the output voltage decays V from the measured output high or output low voltage. The tDECAY value is calculated with test loads CL and IL, and with V equal to 0.5 V.

Output Enable Time
Output pins are considered to be enabled when they have made a transition from a high impedance state to when they start driving. The time for the voltage on the bus to ramp by V is dependent on the capacitive load, CL, and the drive current, ID. This ramp time can be approximated by the following equation:
