NiosII DMA Tutorial

Thanks Cris for replying my post :) I really appreciate it.

Ah.. I just know about this synchronization signal requirement in the DMA data transfer. Well, in my system, the FIFO will be controlled by the Nios processor. The Nios will send read/write signals for FIFO.

Ok, so based on your explanation, can I make a conclusion like this : I should verify the data transfer handled by DMA while integrating the FIFO into my Nios-II system. CMIIW

If my conclusion is correct, can I still use a PIO as an interface between the FIFO and my Nios-II system? or do I have to connect my FIFO directly to my Nios-II system?

The FIFO that I used was designed by MegaFunction, but I also made some modules to control the write and read process of my FIFO. So I hope that I can use the PIO as an interface to my Nios-II system. Otherwise, I have to modify my FIFO :(

Well Cris, your advice make me enthusiastic again to finish this task, thanks! :)
