Abstract
Systems and methods for improving write-back cache performance by utilizing scrubbed state indicators associated with the cache entries. The example system may comprise: a cache comprising a plurality of cache entries; a processing core, coupled to the cache; and a cache controller configured to maintain a plurality of indicators corresponding to a plurality of cache entries, wherein each indicator of the plurality of indicators indicates whether a corresponding cache entry has been scrubbed by synchronizing the cache entry with a next level memory after the cache entry has been modified.
