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.  
Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of  
Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
