CACHING TECHNOLOGIES EMPLOYING DATA COMPRESSION

摘要

Caching technologies that employ data compression are described. The technologies of the present disclosure include cache systems, methods, and computer readable media in which data in a cache line is compressed prior to being written to cache memory. In some embodiments the technologies enable a caching controller to understand the degree to which data in a cache line is compressed, prior to writing the compressed data to cache memory. Consequently the cache controller may determine where the compressed data is to be stored in cache memory based at least in part on the size of the compressed data, a compression ratio attributable to the compressed data (or its corresponding input data), or a combination thereof.
