Abstract
A data processing method includes reading a memory device in response to a read command to respectively read multiple portions of predetermined data; respectively writing the portions in a buffer memory to complete data transfers of the portions of the predetermined data; sequentially providing access information corresponding to each portion of the predetermined data in response to completion of the data transfer of the corresponding portion; obtaining the access information of the predetermined data and accordingly generating multiple descriptors in chronological order of obtaining the access information; receiving and buffering the descriptors in a descriptor pool; sequentially selecting a latest descriptor from the descriptor pool according to a tag value and providing the latest descriptor to a direct memory access engine; and reading the buffer memory according to the latest descriptor to obtain at least a portion of the predetermined data by the direct memory access engine.
