Abstract

A system and method for efficiently processing access requests for a shared resource are described. Each of many requestors are assigned to a partition of a shared resource. When a controller determines no requestor generates an access request for an unassigned partition, the controller permits simultaneous access to the assigned partitions for active requestors. When the controller determines at least one active requestor generates an access request for an unassigned partition, the controller allows a single active requestor to gain exclusive access to the entire shared resource while stalling access for the other active requestors. The controller alternatives exclusive access among the active requestors. In various embodiments, the shared resource is a local data store in a graphics processing unit and each of the multiple requestors is a single instruction multiple data (SIMD) compute unit.
