Abstract:
1. A method of resource arbitration, the method comprising the steps of: defining four priority classes, managed high (MH), managed low (ML), opportunistic high (OH), and opportunistic low (OL), to access one or more resources; assigning a priority class to each resource access request; creating an access request concentrator (ARC) for each resource, through which each resource is accessed; choosing a resource access request at each ARC using the priority order MH, ML, OH, and OL, in decreasing order of priority; determining whether OH priority class resource access requests are locked out; upon a determination that OH priority class resource access requests are locked out, temporarily changing the priority order to OH, OL, MH, and ML, in decreasing order of priority; determining whether OL priority class resource access requests are locked out; and upon a determination that OL priority class resource access requests are locked out, temporarily changing the priority order to MH, OL, OH, and ML, in decreasing order of priority.
