摘要：
Management of access to shared resources within a system comprising a plurality of requesters and a plurality of target resources is provided. A separate arbitration point is associated with each target resource. An access priority value is assigned to each requester. An arbitration contest is performed for access to a first target resource by requests from two or more of the requesters using a first arbitration point associated with the first target resource to determine a winning requester. The request from the winning requester is forwarded to a second target resource. A second arbitration contest is performed for access to the second target resource by the forwarded request from the winning requester and requests from one or more of the plurality of requesters using a second arbitration point associated with the second target resource.
