The TMS320P25 digital signal processor is a member of the TMS320 family of VLSI digital signal processors and peripherals. The TMS320 family supports a wide range of digital signal processing applications, such as telecommunications, modems, image processing, speech processing, spectrum analysis, audio processing, digital filtering, high-speed control, graphics, and other computation intensive applications.
With a 100-ns instruction cycle time and an innovative memory configuration, the '320P25 performs operations necessary for many real-time digital signal processing algorithms. Since most instructions require only one cycle, the TMS320P25 is capable of executing ten million instructions per second. On-chip programmable data/program RAM of 544 words of 16 bits, on-chip program EPROM of 4K words (one-time programmable memory), direct addressing of up to 64K words of external program and 64K words of data memory space, and multiprocessor interface features for sharing global memory minimize unnecessary data transfers to take full advantage of the capabilities of the processor.
