Hi All:

    I want to use the DMA to replace the memcpy() what I using now to improve performance of the system, but I don't know how to do it. I can not find the solution in the IM6Q reference manual. Could you give me the sample code or documents? I'm using IM6Q, linux 3.05 BSP. Thank you.

I have some doubt if the SDMA improves memcpy performance.

Also, the following may be helpful :
