Abstract

Improving access to a cache by a processing unit. One or more previous requests to access data from a cache are stored. A current request to access data from the cache is retrieved. A determination is made whether the current request is seeking the same data from the cache as at least one of the one or more previous requests. A further determination is made whether the at least one of the one or more previous requests seeking the same data was successful in arbitrating access to a processing unit when seeking access. A next cache write access is suppressed if the at least one of previous requests seeking the same data was successful in arbitrating access to the processing unit.
