Arbitration system limiting high priority successive grants.

摘要

Priority levels and bump values are assigned to requestors for access to a system resource. When access requests are received, arbitration of the requests is made in accordance with the assigned priorities, bump values, and the received access requests. If a high priority level access request is granted, then the same request will be held off for a successive number of requests as set by the bump values. In cases where the access is required for more than one request/grant cycle, the priority level access can be retained as long as required. <IMAGE>
