Abstract
Apparatus, methods and systems for controlling data flow between data processing systems. In an example embodiment, the apparatus includes 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 a data processing system, and a pointer descriptor identifying the location in the memory. The apparatus also includes a descriptor table for storing descriptors generated by the descriptor logic for access by the data processing systems.
