dm6467 encoding without OS??

Dear all, I'm starting a new project with DM6467, my customer do not wanna any OS in this system, that means I have to get the encoder work without Linux OS support. I surppose that the arm processor could capture the video independent, and the driver could be developped by CCS debugging tools with no OS support, then the DSP on DM6467 could get the video data in DDR2 and start the encoding processing. I found demos of capturing video by ARM, also deoms run on DSP for encoding YUV files, so I have to find a way to integrate these two parts.

I hope the DM6467 could work in this way, any suggestions?

    Chuangwang,

    Yes it is possible to run the H264 encoder on DM6467 without an OS. There is nothing that prevents you from running the encoder flow without OS. Usually the capture driver is inside the Linux kernel, but if  you do not want the OS you will have to write the driver yourself. Also any synchronization that is required between the ARM and DSP will have to be taken care by the SW developer.

    hello Kapil,

    Thanks for your reply. I'm wonderring if there have somebody have already realized the encoder like what I have mentioned? And, where I could find useful documents and resources? I'm sure it's a hard job to design such a encoder from the very beginning.

    thanks,

    Hi,

    You could use the .C driver files in Linux for your reference when writing the source code of the driver in CCS to save development time. Except for Linux-specific things, the basic behavior should be the same.

    Chuangwang,

    The TI H264 encoder  codec is independent of any OS. You can use the TI codec as it is for your application.

    The TI codecs can be downloaded from:
