ABSTRACT:
A method and structure stores and/or transmits and receives data in compressed form. Retrieval latencies are reduced by selectively transmitting a portion of the data in uncompressed form. When the apparatus is part of a computer architecture supporting main memory compression, a selected L2 cache line belonging to the unit of main memory compression is kept uncompressed. To minimize decompression latency, the uncompressed L2 cache line is stored with the compressed-memory directory. Alternatively, the uncompressed L2 cache line is stored in the compressed memory together with the rest of the memory compression unit it belongs to.
