    Juzheng,

    Is this on your own board or an EVM or other board from TI?

    If there are clock or power requirements, these are taken care of in the GEL file when you use the emulator with the TI board. That is the best starting point for development of your own board. You will then need to adapt those settings to your board.

    You can refer to the Wiki and search for "C6000 training" (no quotes) to find a training class on the use of the DSP. It is based on the similar C6748 DSP.

    Regards,
