ABSTRACT:
In a resource request arbitration apparatus according to the present invention, a request masking unit masks a memory access request REQ that is issued by a resource requesting device at over a minimum frequency needed for the resource requesting device, and an arbitrating unit acknowledges one of the memory access requests RREQ that are not suspended by the request masking unit, 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.
