description

The SMJ320C26 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 SMJ320C26 performs operations necessary for many real time digital signal processing algorithms. Since most instructions require only one cycle, the SMJ320C26 is capable of executing ten million instructions per second. On-chip programmable data/program RAM of 1568 words of 16 bits, on-chip program ROM of 256-words, 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.

The SMJ320C26 scaling shifter has a 16-bit input connected to the data bus and a 32-bit output connected to the ALU. The scaling shifter produces a left shift of 0 to 16 bits on the input data, as programmed in the instruction. The LSBs of the output are filled with zeroes, and the MSBs may be either filled with zeroes or sign-extended, depending upon the status programmed into the SXM (sign-extension mode) bit of status register ST1.
