But the you have to program it with Code Composer and the horrid TI DSP tools. Yeah, ok I've got the older C31 version, not the newer 6x-based DSPs. I'm trying to move the system to Linux, so that others round here can 'share the burden'. I'm designing the boards, drivers, and host software (ACE/C++) at the moment. I need a break! :) I want to avoid spending $20k on the TI tools and an emulator ... hey, call me cheap. However, I like the SCC idea. They sound very similar to the multi-processor links on the Analog Devices SHARC DSPs. More reading :) Dave
