Abstract
An apparatus is disclosed for handling multiple requestors desiring access to a resource. The apparatus includes a plurality of masters and a plurality of arbitrators. Each arbitrator is assigned to a different one of the plurality of masters. Also, each arbitrator is defined to consider a different portion of the multiple requestors when selecting a requestor to be serviced by the master to which the arbitrator is assigned. Each arbitrator is further defined to select a requestor from the different portion of the multiple requestors, such that selection of a particular requestor is not duplicated among the plurality of arbitrators. Additionally, requestor selection by each of the plurality of arbitrators is performed in a same clock cycle.
