摘要：
Chaining or cascading two or more DMA devices to perform DMA transfers across common buses. DMA devices are modified to act as a bus slave relative to another DMA bus master device so that information can be transferred from one bus to another across a third bus common to the DMA devices. The slave DMA can cause the master DMA to stop sending data to limit the bandwidth requirements of the common bus.
