Hello Brad,

I have created a custom SOPC component that makes use of the DMA as a READ and WRITE MASTER, with the component just a read slave. The READ portion of the DMA is conected to memory, SRAM in my case, and the WRITE portion is connected to my logic.

I used the streaming mode of transfer for packets and a MEGA WIZARD for my fifo. I have a little logic that helps pace the incoming data to the WRITE portion of the FIFO.

It works fine.
