ABSTRACT:
An access request arbitration section, a data amount management section and a resource control section are provided between a plurality of masters and a shared resource. The data amount management section manages access data amounts passing between the plurality of masters and the resource. The access request arbitration section executes arbitrary arbitration of issuing access permission to a master determined according to the access data amount at any timing, in addition to periodic arbitration of issuing access permission to any of the masters at fixed-interval arbitration timing. If an access request of less than a defined data amount is granted in periodic arbitration, the remaining access chance can be used in arbitrary arbitration.
