PROBLEM TO BE SOLVED: To make transferring performance of a transaction uniform between all nodes, in a system having a structure connected with a plurality of crossbar switches in multi-stage.;SOLUTION: In the crossbar switches L0 to L5, a routing table outputs an output port number and priority in arbitrating a crossbar switch, when indexed by a processor/IO node number of a transaction issuing origin and a processor/IO node number of a transaction transfer destination. A selector takes out the output port number and the priority from the routing table on the basis of the processor/IO node number of a transaction issuing origin and the processor/IO node number of a transaction transfer destination, when transaction is inputted from an input port. An arbitrating circuit corresponding to the output port number conducts arbitration processing according to the taken out priority.;COPYRIGHT: (C)2004,JPO
