    摘要: A method comprising generating a transfer configuration descriptor (“TCD”), said TCD comprising information pertaining to data to be transferred. The method further comprises dynamically configuring a direct memory access (“DMA”) channel based on said TCD without using a CPU and transferring a group of data blocks by way of said DMA channel.
