PROBLEM TO BE SOLVED: To provide a resource request arbitration device that controls the service qualities for each resource requesting device based on a predetermined static priority order, without concerning a relation among resource requesting devices other than the priority order. SOLUTION: In the resource request arbitration device, request masking units 50, 51 mask a memory access request REQ that is issued by resource requesting devices 80, 81 at over a minimum frequency needed for the resource requesting device, and an arbitrating unit 40 acknowledges one of the memory access requests RREQ that are not suspended by the request masking units 50, 51, based on a predetermined static order of priority. With this resource request arbitration apparatus, the arbitrating unit do not have to concern anything other than the predetermined priority order among the memory access requesting units, and an easy and plain arbitration system based on the static priority order ensures the minimum frequency for acknowledging the resource requests that each memory access requesting unit needs.
