摘要：
Apparatus is described for controlling flow of data between first and second data processing systems via a memory. The apparatus comprises descriptor logic for generating a plurality of descriptors including a frame descriptor defining a data packet to be communicated between a location in the memory and the second data processing system, and a pointer descriptor identifying the location in the memory. The apparatus also comprises a descriptor table for storing the descriptors generated by the descriptor logic for access by the first and second data processing systems.
