DMA Controller

Jump to solution

What is the difference between DMA Controller and Pixel Buffer DMA Controller?  , I think both of them for retrieve and store for video frames from memory. How can I use these with the SDRAM controller?

Any help would be greatly appreciated.

  1. DMA controller IP - Generic used for data transfer (not limited to video data) which interact with PCIe IP and memory IP. Example of reference design link


Thanks.
