Abstract
Methods, devices and systems for a compressor and a decompressor for encoding and decoding data in the cache/memory/data transferring subsystem in a computer system or in a communication network are described herein. An example variable-length compressor is able to compress blocks of data values and the compressed blocks may include mixes of compressed and uncompressed values, wherein metadata in the form of a unique special-meaning codeword (UUIC) indicates uncompressed values. An example variable-length decompressor is able to decompress the compressed data blocks. The compressor and decompressor are able to support compression and decompression of common compression scenarios that are used in combination with variable-length compression to improve compressibility in the cache/memory/data transferring subsystem in a computer system or in a communication network.
