Hello, the short answer is that it is hard to put an image into the frame buffer and that you probably should not be doing it. The frame buffer is useful to solve throughput and rate conversion issues but you cannot use it just to read things from memory. The VIP User guide describes how the frame buffer manages the buffers in memory and how these buffers are exchanged between a writer module and a reader module. This algorithm implies that the frame buffer can only read back the video frames it received from its Avalon-Streaming input. You might want to check out the scatter-gather DMA IP as this might be more appropriate to meet your needs. vgs
