I'm working on a project for my capstone course that uses audio signal processing. I'm trying to find resources on how to use TI's TAS3204 DSP but can't find much other than the datasheet. If anyone has experience programming this piece of hardware I'd be really grateful for any help.

You can start at the TI E2E forums:
