Maintaining forward progress in a shared L2 by detecting and breaking up requestor starvation

A system having a plurality of arbitration levels for detecting and breaking up requester starvation, the system including: a plurality of logic circuits, each of the plurality of logic circuits permitted to access a cache via a plurality of requesters for requesting information from the cache; a counter for counting a number of times each of the plurality of requesters of each of the plurality of logic circuits has successfully accessed one or more of the plurality of arbitration levels and has been rejected by a subsequent arbitration level; wherein if the counter reaches a predetermined threshold for a requester of a logic circuit, the counter triggers an event that increases a priority level of the requester compared to all other requesters attempting to access the cache, so that the requestor reaches the cache before the other requesters.
