Abstract
One embodiment of the present invention sets forth a technique for arbitrating requests received by an L1 cache from multiple clients. The L1 cache outputs bubble requests to a first one of the multiple clients that cause the first one of the multiple clients to insert bubbles into the request stream, where a bubble is the absence of a request. The bubbles allow the L1 cache to grant access to another one of the multiple clients without stalling the first one of the multiple clients. The L1 cache services multiple clients with diverse latency and bandwidth requirements and may be reconfigured to provide memory spaces for clients executing multiple parallel threads, where the memory spaces each have a different scope.
