houston, texas 772511443 cpu description the cpu fetches velociti advanced very-long instruction words (vliw) (256 bits wide) to supply up to eight 32-bit instructi ons to the eight functional units during every clock cycle. the velociti vliw architecture features controls by which all eight units do not have to be supplied with instructions if they are not ready to execute. the first bit of every 32-bit instruction determines if the next instruction belongs to the same execute packet as the previous instruction, or whether it should be executed in the following clock as a part of the next execute packet. fetch packets are always 256 bits wide; however, the execute packets can vary in size. the variable-length execute packets are a key memory-saving feature, distinguishing the 'c67x cpu from other vliw architectures. the cpu features two sets of functional units. each set contains four units and a register file. one set contains functional units .l1, .s1, .m1, and .d1; the other set contains units .d2, .m2, .s2, and .l2. the two register files contain 16 32-bit registers each for the total of 32 general-purpose registers. the two sets of functional units, along with two register files, compose sides a and b of the cpu (see the functional and cpu block diagram and figure 1). the four functional units on each side of the cpu can freely share the 16 registers belonging to that side. additionally, each side features a single data bus connected to all registers on the other side, by which the two sets of functional units can access data from the register files on opposite sides. while register access by functional units on the same side of the cpu as the register file can service all the units in a single clock cycle, register access using the register file across the cpu supports one read and one write per cycle. the 'c67x cpu executes all tms320c62x ? dsp fixed-point instructions. in addition to the 'c62x dsp fixed-point instructions, the six out of eight functional units (.l1, .m1, .d1, .d2, .m2, and .l2) also execute floating-point instructions. the remaining two functional units (.s1 and .s2) also execute the new lddw instruction which loads 64 bits per cpu side for a total of 128 bits per cycle. another key feature of the 'c67x cpu is the load/store architecture, where all instructions operate on registers (as opposed to data in memory). two sets of data-addressing units (.d1 and .d2) are responsible for all data transfers between the register files and the memory. the data address driven by the .d units allows data addresses generated from one register file to be used to load or store data to or from the other register file. the 'c67x cpu supports a variety of indirect-addressing modes using either linear- or circular-addressing modes with 5- or 15-bit offsets. all instructions are conditional, and most can access any one of the 32 registers. some registers, however, are singled out to support specific addressing or to hold the condition for conditional instructions (if the condition is not automatically atrueo). the two .m functional units are dedicated for multiplies. the two .s and .l functional units perform a general set of arithmetic, logical, and branch functions with results available every clock cycle. the processing flow begins when a 256-bit-wide instruction fetch packet is fetched from a program memory. the 32-bit instructions destined for the individual functional units are alinkedo together by a1o bits in the least significant bit (lsb) position of the instructions. the instructions that are achainedo together for simultaneous execution (up to eight in total) compose an execute packet. a a0o in the lsb of an instruction breaks the chain, effectively placing the instructions that follow it in the next execute packet. if an execute packet crosses the fetch-packet boundary (256 bits wide), the assembler places it in the next fetch packet, while the remainder of the current fetch packet is padded with nop instructions. the number of execute packets within a fetch packet can vary from one to eight. execute packets are dispatched to their respective functional units at the rate of one per clock cycle and the next 256-bit fetch packet is not fetched until all the execute packets from the current fetch packet have been dispatched. after decoding, the instructions simultaneously drive all active functional units for a maximum execution rate of eight instructions every clock cycle. while most results are stored in 32-bit registers, they can be subsequently moved to memory as bytes or half-words as well. all load and store instructions are byte-, half-word, or word-addressable. tms320c62x is a trademark of texas instruments. sprs067e may 1998 revised may 2000 6 post office box 1443 ?

dsp family member has one of three prefixes: tmx, tmp, or tms. t exas instruments recommends two of three possible prefix designators for support tools: tmdx and tmds. these prefixes represent evolutionary stages of product development from engineering prototypes (tmx/tmdx) through fully qualified production devices/tools (tms/tmds). device development evolutionary flow: tmx experimental device that is not necessarily representative of the final device's electrical specifications tmp final silicon die that conforms to the device's electrical specifications but has not completed quality and reliability verification tms fully qualified production device support tool development evolutionary flow: tmdx development-support product that has not yet completed t exas instruments internal qualification testing. tmds fully qualified development-support product tmx and tmp devices and tmdx development-support tools are shipped against the following disclaimer: adevelopmental product is intended for internal evaluation purposes.o tms devices and tmds development-support tools have been characterized fully, and the quality and reliability of the device have been demonstrated fully. ti's standard warranty applies. predictions show that prototype devices (tmx or tmp) have a greater failure rate than the standard production devices. t exas instruments recommends that these devices not be used in any production system because their expected end-use failure rate still is undefined. only qualified production devices are to be used. ti device nomenclature also incl udes a suffix with the device family name. this suffix indicates the package type (for example, gjc), the temperature range (for example, blank is the default commercial temperature range), and the device speed range in megahertz (for example, -167 is 167 mhz). table 2 identifies the available tms320c6701 devices by their associated orderable part numbers (p/ns) and gives device-specific ordering information (for example, device speeds, core and i/o supply voltage values, and device operating temperature ranges). figure 4 provides a legend for reading the complete device name for any tms320 ?
