摘要：In one embodiment of the present invention a cache unit organizes data stored

in an attached memory to optimize accesses to compressed data. In operation, the cacheunit introduces a layer of indirection between a physical address associated with amemory access request and groups of blocks in the attached memory. The layer ofindirection—virtual tiles—enables the cache unit to selectively store compressed datathat would conventionally be stored in separate physical tiles included in a group ofblocks in a single physical tile. Because the cache unit stores compressed data associatedwith multiple physical tiles in a single physical tile and, more specifically, in adjacentlocations within the single physical tile, the cache unit coalesces the compressed data intocontiguous blocks. Subsequently, upon performing a read operation, the cache unit mayretrieve the compressed data conventionally associated with separate physical tiles in asingle read operation.
