A streaming direct memory access (DMA) engine is disclosed. The streaming DMA engine includes several power reduction capabilities. A controller throttles the DMA engine according to the system throughput requirement and the system processor operation state. The DMA engine holds off a new read request to the memory if the data present in the DMA engine requires retransmission. The DMA engine holds off a new write request to the memory if the data present in the DMA engine is corrupted, until the corrupted data is discarded.
