I already have support for a TI chip like that (the C5471) and also for an ARM9 with C5 DSP (DM320). See http://focus.ti.com.cn/cn/lit/ml/sprt239/sprt239.pdf I have a c5 DSP bridge driver somewhere around on my backup disks as well. I never released it into NuttX because there was never any need. Perhaps that could be useful now. Somewhere I also have tools that will convert the TI proprietary object files and logic to manage loading different programs into the DSP. The bridge also supports communication channels to communicate with the DSP. Greg
