amd p r e l i m i n a r y 8 AM29200 and am29205 risc microcontrollers i/o port the AM29200 microcontroller's i/o port permits direct access to 16 individually programmable external input/ output signals. eight signals are available on the am29205 microcontroller. these eight signals can be configured to cause interrupts on either microcontroller. serializer/deserializer the bidirectional bit serializer/deserializer (video inter- face) permits direct connection to a number of laser marking engines, video displays, or raster input devices such as scanners. serial port the serial port implements a full-duplex uart. parallel port the parallel port implements a bidirectional ibm pc- compatible parallel interface to a host processor. wide range of price/performance points to reduce design costs and time-to-market, one basic system design can be used as the foundation for an en- tire product line. from this design, numerous imple- mentations of the product at various levels of price and performance may be derived with minimum time, effort, and cost. the AM29200 and am29205 microcontrollers provide this capability through programmable memory widths, burst-mode and page-mode access support, program- mable wait states, and hardware and 29k family soft- ware compatibility. a system can be upgraded without hardware and software redesign using various memory architectures. the rom controller on the am29205 microcontroller ac- commodates memories that are either 8 or 16 bits wide, while that of the AM29200 microcontroller supports either 8-, 16-, or 32-bit memories. the dram controller on the am29205 microcontroller accommodates dynamic memories that are 16 bits wide; the AM29200 micro- controller supports either 16- or 32-bit memories. these unique features provide a flexible interface to low-cost memory as well as a convenient, flexible up- grade path. for example, a system can start with a 16-bit memory design and can subsequently improve perfor- mance by migrating to a 32-bit memory design. one par- ticular advantage is the ability to add memory in half-megabyte increments. this provides significant cost savings for applications that do not require larger memory upgrades. the AM29200 microcontroller family allows users to ad- dress a wide range of cost performance points, with higher performance and lower cost than existing de- signs based on cisc microprocessors. glueless system interfaces the AM29200 and am29205 microcontrollers minimize system cost by providing a glueless attachment to exter- nal roms, drams, and other peripheral components. processor outputs have edge-rate control that allows them to drive a wide range of load capacitances with low noise and ringing. this eliminates the cost of external logic and buffering. bus- and binary-compatibility compatibility within a processor family is critical for achieving a rational, easy upgrade path. the AM29200 and am29205 microcontrollers are members of a bus- compatible family of risc microcontrollers, which also includes the high-performance am29240, am29245, and am29243 microcontrollers. future members of this family will improve in price and performance and system capabilities without requiring that users redesign their system hardware or software. bus compatibility ensures a convenient upgrade path for future systems. the AM29200 microcontroller is binary compatible with the am29240, am29245, and am29243 microcontrollers, as well as the am29000, am29005, am29030, am29035, and am29050 microprocessors. the AM29200 micr ocon- troller family provides a migration path to low-cost, highly integrated systems for products based on other 29k family microprocessors, without requiring expensive re- writes of application software. complete development and support environment a complete development and support environment is vi- tal for reducing a product's time-to-market. advanced micro devices has created a standard development en- vironment for the 29k family of processors. in addition, the fusion29k third-party support organization provides the most comprehensive customer/partner program in the embedded processor market. advanced micro devices offers a complete set of hard- ware and software tools for design, integration, debug- ging, and benchmarking. these tools, which are available now for the 29k family, include the following: high c 29k optimizing c compiler with assem- bler, linker, ansi library functions, and 29k archi- tectural simulator xray29k tm source-level debugger minimon29k tm debug monitor a complete family of demonstration and develop- ment boards in addition, advanced micro devices has developed a standard host interface (hif) specification for operating system services, the universal debug interface (udi) for seamless connection of debuggers to ices and target
amd p r e l i m i n a r y 9 AM29200 and am29205 risc microcontrollers hardware, and extensions for the unix common object file format (coff). this support is augmented by an engineering hotline, an on-line bulletin board, and field application engineers. performance overview the AM29200 and am29205 microcontrollers offer a significant margin of performance over cisc micropro- cessors in existing embedded designs, since the majority of processor features were defined for the maximum achievable performance at a very low cost. this sec- tion describes the features of the AM29200 and am29205 microcontrollers from the point of view of system performance. instruction timing the AM29200 and am29205 microcontrollers use an arithmetic/logic unit, a field shift unit, and a prioritizer to execute most instructions. each of these is organized to operate on 32-bit operands and provide a 32-bit result. all operations are performed in a single cycle. the performance degradation of load and store opera- tions is minimized in the AM29200 and am29205 micro- controllers by overlapping them with instruction execution, by taking advantage of pipelining, and by or- ganizing the flow of external data into the processor so that the impact of external accesses is minimized. pipelining instruction operations are overlapped with instruction fetch, instruction decode and operand fetch, instruction execution, and result write-back to the register file. pipeline forwarding logic detects pipeline dependencies and routes data as required, avoiding delays that might arise from these dependencies. pipeline interlocks are implemented by processor hard- ware. except for a few special cases, it is not necessary to rearrange programs to avoid pipeline dependencies, although this is sometimes desirable for performance. burst-mode and page-mode memories the AM29200 microcontroller directly supports burst- mode memories in rom address space. the burst- mode memory supplies instructions at the maximum bandwidth, without the complexity of an external cache or the performance degradation due to cache misses. both the AM29200 and am29205 microcontrollers can also use the page-mode capability of common drams to improve the access time in cases where page-mode accesses can be used. this is particularly useful in very low-cost systems with 16-bit-wide drams, where the dram must be accessed twice for each 32-bit operand. instruction set overview the AM29200 and am29205 microcontrollers employ a three-address instruction set architecture. the compiler or assembly-language programmer is given complete freedom to allocate register usage. there are 192 gen- eral-purpose registers, allowing the retention of inter- mediate calculations and avoiding needless data destruction. instruction operands may be contained in any of the general-purpose registers, and the results may be stored into any of the general-purpose registers. the instruction set contains 117 instructions that are di- vided into nine classes. these classes are integer arith- metic, compare, logical, shift, data movement, constant, floating point, branch, and miscellaneous. the floating- point instructions are not executed directly, but are emu- lated by trap handlers. all directly implemented instructions are capable of executing in one processor cycle, with the exception of interrupt returns, loads, and stores. data formats the AM29200 and am29205 microcontrollers define a word as 32 bits of data, a half-word as 16 bits, and a byte as 8 bits. the hardware provides direct support for word- integer (signed and unsigned), word-logical, word-bool- ean, half-word integer (signed and unsigned), and character data (signed and unsigned). word-boolean data is based on the value contained in the most significant bit of the word. the values true and false are represented by the msb values 1 and 0, respectively. other data formats, such as character strings, are sup- ported by instruction sequences. fl oating-point formats (single and double precision) are defined for the proces- sor; however, there is no direct hardware support for these formats in the AM29200 or am29205 microcontroller. protection the AM29200 and am29205 microcontrollers offer two mutually exclusive modes of execution, the user and supervisor modes, that restrict or permit accesses to certain processor registers and external storage locations. the register file may be configured to restrict accesses to supervisor-mode programs on a bank-by-bank basis. dram mapping the AM29200 and am29205 microcontrollers provide a 16-mbyte region of virtual memory that is mapped to one of four 64-kbyte blocks in the physical dram memory. this supports system functions such as on-the-fly data compression and decompression, allowing a large data
amd p r e l i m i n a r y 10 AM29200 and am29205 risc microcontrollers structure such as a frame buffer to be stored in a com- pressed format while the application software operates on a region of the structure that is decompressed. using a mechanism that is analogous to demand paging, sys- tem software moves data between the compressed and decompressed formats in a way that is invisible to the application software. this feature can greatly reduce the amount of memory required for printing, imaging, and graphics applications. interrupts and traps when the microcontroller takes an interrupt or trap, it does not automatically save its current state information in memory. this lightweight interrupt and trap facility greatly improves the performance of temporary inter- ruptions such as simple operating-system calls that re- quire no saving of state information. in cases where the processor state must be saved, the saving and restoring of state information is under the control of software. the methods and data structures used to handle interruptseand the amount of state in- formation savedemay be tailored to the needs of a par- ticular system. interrupts and traps are dispatched through a 256-entry vector table which directs the processor to a routine that handles a given interrupt or trap. the vector table may be relocated in memory by the modification of a proces- sor register. there may be multiple vector tables in the system, though only one is active at any given time. the vector table is a table of pointers to the interrupt and trap handlers and requires only 1 kbyte of memory. the processor performs a vector fetch every time an inter- rupt or trap is taken. the vector fetch requires at least three cycles, in addition to the number of cycles required for the basic memory access. debugging and testing software debugging on the AM29200 and am29205 mi- crocontrollers is facilitated by the instruction trace facil- ity and instruction breakpoints. instruction tracing is accomplished by forcing the processor to trap after each instruction has been executed. instruction breakpoints are implemented by the halt instruction or by a soft- ware trap. the AM29200 microcontroller provides two additional features to assist system debugging and testing: the test/development interface is composed of a group of pins that indicate the state of the proces- sor and control the operation of the processor. an ieee std. 1149.11990 (jtag) compliant stan- dard test access port and boundary-scan archi- tecture provides a scan interface for testing system hardware in a production environment. it contains extensions that allow a hardware-development system to control and observe the processor with- out interposing hardware between the processor and system. hardware testing and debugging on the am29205 micro- controller are supported by using an AM29200 microcon- troller to emulate an am29205 microcontroller.
