Zusammenfassung:The present invention provides for independent source-read and destination-write functionality for Enhanced Direct Memory Access (EDMA). Allowing source read and destination write pipelines to operate independently makes it possible for the source pipeline to issue multiple read requests and stay ahead of the destination write for fully pipelined operation. The result is that fully pipelined capability may be achieved and utilization of the full DMA bandwidth and maximum throughput performance are provided.
