Use of compression to increase the capacity of a memory-side cache with a large block size

摘要

Systems, apparatus, and methods may be provided for identifying a first block and a second block, the first block having a first plurality of cache lines, the second block having a second plurality of cache lines, and the second block being in a memory side Cache is located. In addition, each cache line in the first plurality of cache lines may be compressed with a corresponding cache line in the second plurality of cache lines to obtain a compressed block having a third plurality of cache lines. In one example, the second block in the memory-side cache is replaced with the compressed block if the compressed block satisfies a size constraint.
