Abstract
In accordance with one aspect of the present invention, an access request associated with a cache miss to a single cache line having a pending cache fill can be handled in a non-blocking manner by storing the cache miss in a retry queue while the cache fill is pending. The retry queue then detects the return of the cache fill and inserts the access request associated with the cache miss onto the cache pipeline for processing.
