Hi Ti!

The use of TMS320C6748 on the Camera image acquisition is VPIF0 FIFO, EDMA3 buffer display, how to use the EDMA3 management C6748 follows memory every piece of data?

=============The temporary buffer, for image processing=======

Uint32 tempSrcYbuffer =0x80200000; //Y

Uint32 tempSrcCbbuffer =0x802675c0; //Cb

The starter lib hadn't "Uint32" type?

Please restate your question with a lot more detail. It is not clear what you are asking.

In the C6748 buffer is EDMA3 can also use the "csl_dat.h" lib function DAT_copy (void*src, void*dst, Uint16 (byteCnt)? in the C6748 starter lib can‘t (void*src, void*dst, Uint16 (byteCnt）？

How to the used EDMA3 copy many menory data in c6748? follows is c642x of code,How to transplant C6748?

while(capNewFrame == 0){}

capNewFrame =0;
for(i=0;i<numLines;i++)
{capNewFrame =0;
for(i=0;i<numLines;i++)
{DAT_copy((void *)(capYbuffer + i * numPixels),
              (void *)(tempDisYbuffer + i * numPixels),
              numPixels);
} for(i=0;i<numLines;i++)
{DAT_copy((void *)(tempDisYbuffer + i * numPixels),
              (void *)(disYbuffer + i * numPixels),
              numPixels);
}

for(i=0;i<0x33ae0;i++)
      {
           *((Uint8 *)(disCrbuffer +i)) =0x80;
           *((Uint8 *)(disCbbuffer +i)) =0x80;

      }
for(i=0;i<numLines;i++)
          {       DAT_copy((void *)(capYbuffer + i * numPixels),
                   (void *)(tempSrcYbuffer + i * numPixels),
                    numPixels);
