Summary:A method and apparatus for making DMA transfers where the DMA engine runs autonomously, thereby reducing the extent of dependence on a controlling processor. The processor determines when there are blocks of data, in a data stream, which could form similar or repetitive DMA transfers and supplies information regarding such transfers to a DMA engine. This enables the DMA engine to run autonomous so that successive blocks of data are cyclically transferred to memory.
