Abstract
A caching technique involves receiving a cache request to move data into a cache (or a particular cache level of a cache hierarchy), and generating a comparison between content of the data and content of other data already stored within the cache. The caching technique further involves providing a caching response based on the comparison between the content of the data and the content of the other data already stored within the cache. The caching response includes refraining from moving the data into the cache when the comparison indicates that the content of the data is already stored within the cache. The caching response includes moving the data into the cache when the comparison indicates that the content of the data is not already stored within the cache. Such a technique is capable of eliminating data redundancies within a cache (or within a particular cache level of a cache hierarchy).
