description
The TMP / SMJ320C40KGD DSP is a 32-bit, floating-point processor manufactured in 0.72-µm, double-level
metal CMOS technology. It is the fourth generation of DSPs from Texas Instruments, and it is the world’s first
DSP designed for parallel processing. The on-chip parallel processing capabilities of the ’C40 make the
floating-point performance required by many applications achievable and cost-effective.
The TMP / SMJ320C40 is the first DSP with on-chip communication ports for processor-to-processor
communication using simple communication software with no external hardware. This allows connectivity with
no external glue logic. The communication ports remove I/O bottlenecks, and the independent smart-DMA
coprocessor is able to handle the CPU I/O requirements.
