    FX3 GPIF Config for Audio+Video application

    harshad_1712281

      Hi,

         

      I am using an A/V source connected to a decoder chip which splits them both. The video output enters FPGA and is buffered as needed for the FX3 GPIF to process it for UVC. This part all works fine. 

         

      However, now I need to also handle the audio and make it a part of the input stream to GPIF. But, I'm confused how to insert audio in the middle of the video stream on the D0 to D31 bit lines (FX3 GPIF input pins) without damaging the video stream and ensuring that the Windows USB Driver on PC (USB Host) is able to read it and play it successfully.

         

      Any insight in this matter would be helpful.

         

      Thanks,

         

      Harshad.
