Patent abstract
A method and an apparatus are provided for prefetching data from a system memory to a cache for a direct memory access (DMA) mechanism in a computer system. A DMA mechanism is set up for a processor. A load access pattern of the DMA mechanism is detected. At least one potential load of data is predicted based on the load access pattern. In response to the prediction, the data is prefetched from a system memory to a cache before a DMA command requests the data.
