Abstract:
A method for using a programmable DMA engine to implement memory transfers and video processing for a video processor. A DMA control program is configured for controlling DMA memory transfers between a frame buffer memory and a video processor. The DMA control program is stored in the DMA engine. A DMA request can be received from the video processor. The DMA control program is executable to implement the DMA request for the video processor. The DMA engine is operable to execute low-level command for accessing the frame buffer memory to implement a high-level command.
