SMJ320C40KGDD 浮点 DSP 已知性能良好芯片

The 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 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.
