摘要
A system including a DMA controller for dynamically varying the size of DMA transfers. The controller includes means for buffering data blocks from the device as they arrive and means for dynamically activating a DMA operation and for varying the amount of data transferred on a DMA operation depending on the recent arrival rate of data and the amount of data already buffered for DMA transfer.
