    LorryAstra
    Hi Juan, I feel that it is better to develop DSP algorithm in Linux than in Windows CCS. I try to revise some code in "videnc_copy" example in codecs, and then I compile it with XDC tools. After that, I apply this new algorithm in encodedecode demo. Everything sounds good. Could you tell...

    Juan Gonzales
    Bob, The post Lorry pointed you to has some good information on developing DSP algorithms. In my humble opinion, the best way to get started is to look at the sample source code under codec_engine_X_XX_XX_XX directory which is part of the DVSDK software installation. You will be able to find very simple...

    LorryAstra
    Hi BMillikan, (I suppose that you use EVM6446.) I think if you want to access CMEM memory from DSP side, 1. First of all you should let DSP jump out from "reset" state. 2. To find a way to tell DSP that where DSP can find the pointer of contiguous memory allocated from ARM app. I...

    Well, as the transfers are not blocking, you have to wait for the previous transfer to be completed before submitting a new one. This can be accomplished by inserting a while loop before the dc_readblock() statement: #define ADS8364_STAT_NOTINIT (-1) #define ADS8364_STAT_READY ( 0) #define ADS8364_STAT_RUN...
