Abstract
A system and method for efficiently scheduling requests. In various embodiments, a processor sends commands such as read requests and write requests to an arbiter. The arbiter reduces latencies between commands being sent to a communication fabric and corresponding data being sent to the fabric. When the arbiter selects a given request, the arbiter identifies a first subset of stored requests affected by the given request being selected. The arbiter adjusts one or more attributes of the first subset of requests based on the selection of the given request. In one example, the arbiter replaces a weight attribute with a value, such as a zero value, indicating the first subset of requests should not be selected. Therefore, during the next selection by the arbiter, only the requests in a second subset different from the first subset are candidates for selection.
