By the way you need a sync point here. Or really bad things happen. (Bad things is ambiguous intentionally!) I also agree with katak255 you do not really need DMA for this one.

If you want I can show you how to use DMA with a sync point. The problem with that is it ends up creating a scheduling problem. This is a very large topic because of all the bad things. It represents an optimization that can go wrong very quickly. There actually is a way through the forest.
