Abstract
An arbiter in a communication system including a plurality of request shapers in communication with a plurality of requestors. Each request shaper is configured to receive a request for access to a resource of the communication system, initially assign a priority level to the request upon receipt of the request, increase an age of the request, after increasing the age of the request, compare the age of the request to a delta period value associated with the respective requestor, and repeatedly increase the priority level of the request based on the comparison. Each of the plurality of requestors has a corresponding delta period value that is different from that of other ones of the plurality of requestors. An arbiter core is configured to grant one of the plurality of requestors access to the resource based on the priority level of each request and the age of each request.
