The following is the opinion of one software developer.
TI makes feature rich DSPs. But buyer beware!
The problems start when it is time to program the device. Despite filling several shelves, programmers can spend weeks learning the toolsets and searching out the missing details to accomplish routine tasks.
The network development kit (NDK) presensts another caveat emptor. The NDK images are large. The manuals mention the possibility of omitting some components, but just try to find out to do it.
The on chip boot loader does not support emac, and none is provided for SPI connected flash.
Summing up, the C674x may be a great chip. But software documentation drops the ball, despite the page count. As a result, the schedule and cost risksm can be significant.
