Packet communication control device, a memory access control device, and an information-processing system

摘要

A packet communication control device transfers a control packet and a data packet and includes a plurality of sending units and a multiplexer which separates a data communication path and a control communication path, multiplexes the control packets and transfers the multiplexed control packets by the control communication path and the data packet by the data control path. The average Round Trip communication time can be shortened and the hardware cost can be reduced because the Shortest-Job-First control is implemented by separating data communication pathway from control communication pathway logistically or physically, and also multiplexing the control communication pathway with control packet.
