TWO DIMENSIONAL DIRECT MEMORY ACCESS SCHEME FOR ENHANCED NETWORK PROTOCOL PROCESSING PERFORMANCE

摘要

Systems and methods are directed to a memory device that includes a plurality of memory buffers and a direct memory access (DMA) descriptor structure. The DMA descriptor structure comprises a transfer command and associated data transfer information and encryption/decryption information that is configured in a two dimensional, tree-linked structure. A DMA controller that is communicatively coupled to the memory device transfers data to/from the memory buffers and encrypts/decrypts the data based on the transfer command and data transfer information and encryption/decryption information provided by the two dimensional, tree-linked DMA descriptor structure.
