DMA Controller - DMA Controller 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. Replies: Re: DMA Controller HI, I would say the difference are like below in high level overview 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 https://www.intel.com/content/dam/www/programmable/us/en/pdfs/literature/an/an829.pdf Pixel buffer DMA controller IP - Custom IP used for video data transfer. Part of video IP core suite in Intel FPGA University Program. You can checkout the IP user guide doc and some reference design in below link https://www.intel.com/content/www/us/en/programmable/support/training/university/materials-computer-systems.html Thanks.
