SMJ320C40KGDC 浮点数字信号处理器，军用已知合格芯片

The TMP/ SMJ320C40KGD DSP is a 32-bit, floating-point processor manufactured in 0.72-um, double-level metal CMOS technology. It is the fourth generation of DSPs from Texas Instruments, and it is the world\x92s first DSP designed for parallel processing. The on-chip parallel processing capabilities of the \x92C40 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
