ABSTRACT:
A routing switch for constructing an interconnection network of a parallel processing computer is disclosed. A purpose of the present invention is to provide a crossbar routing switch for a hierarchical interconnection network which has an expandability of a data length and an expandability of a hierarchical structure. The crossbar routing switch for a hierarchical interconnection network in accordance with the present invention comprises a predetermined number of input control units for controlling one input port to perform the manipulation of input data; a crossbar core unit for analyzing a data transmission request by the input control unit and outputting the corresponding data; and a predetermined number of output control unit for controlling one output port and receiving the output data from the crossbar core unit to output it to the output port. The present invention has advantages over the prior art that a data expandability can be provided by simply adding a routing switch without re-designing or re-manufacturing the routing switch several times, and that it can be suitably adapted to an interconnection network of a parallel processing system which requires a high expandability and high performance.
