DescriptionTexas Instruments TMS320 Series Digital Signal ProcessorsThe TMS320 family of 16/32-bit single-chip digital signal processors combines the flexibility of a high-speed controller with the numerical capability of an array processor, thereby offering an inexpensive alternative to multichip bit-slice processors. The highly paralleled architecture and efficient instruction set provide speed and flexibility to produce a MOS microprocessor family that is capable of executing more than 12.5 MIPS (million instructions per section). The TMS320 family optimizes speed by implementing functions in hardware that other processors implement through microcode or software. This hardware-intensive approach provides the design engineer with processing power previously unavailable on a single chip.The TMS320 family consists of three generations of digital signal processors. The first generation contains the TMS32010 and its spinoffs. The second generation includes the TMS32020, TMS320C25, and TMS320E25, which are described in this data sheet. The TMS320C30 is a floating-point DSP device designed for even higher performance. Many features are common among the TMS320 processors. Specific features are added in each processor to provide different cost/performance tradeoffs. Software compatibility is maintained throughout the family to protect the user’s investment in architecture. Each processor has software and hardware tools to facilitate rapid design.
