    摘要: A method for resolving address contention and prioritization of access to resources within a shared memory system includes dynamically creating ordered lists of requests for each contested resource. A new request is added to the lists only after a conflict is recognized. Since the resource conflict does not always exist, there is no impact to a request for an uncontested resources.

    摘要: A resource arbitration system is provided implementing a modified round robin priority selection logic including resource checking and lockout avoidance that updates the round robin priority token only when (1) the process request is granted and (2) there are no prior processes with resource conflicts. The resource arbitration system thereby allows each process request to get into the queue with high priority once the requested resource is freed.
