description
The TMP/SMJ320C40KGD DSP is a 32-bit, floating-point processor manufactured in 0.72-
μ
m, 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 input/output bottlenecks, and the independent
smart-DMA coprocessor is able to handle the CPU input/output 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.
PRODUCTION DATA information is current as of publication date.
Products conform to specifications per the terms of Texas Instruments
standard warranty. Production processing does not necessarily include
testing of all parameters.
