ABSTRACT:
A method for transferring DMA data between the video port and the host interface in a multimedia processor is disclosed. The method includes determining whether one frame data should be transferred between the host interface and the video port; preloading some DMA instructions in the frame buffer and setting the DMA register to be fitted for the DMA operation; and fetching the preloaded instructions from the frame buffer subsequently by the DMA controller to perform video data transfer at a predetermined data bandwidth. According to this invention, the time consumption of a microprocessor for programming the DMA controller is reduced, thereby enhancing the data transfer rate between the host interface and video port of the multimedia computer system.
