METHODS, DEVICES AND SYSTEMS FOR COMPRESSING AND DECOMPRESSING DATA

Methods, devices and systems extend 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. Example variable-length compressors and decompressors are extended with new features to: compress more densely when specific values occur in specific positions in a data block; to improve compression and decompression latency when specific values that are appear frequent occur in a data block; to also improve decompression latency by recording the lengths of variable-length encoded values of a compressed data block. Said compressor and decompressor are extended to support compression and decompression of common compression scenarios that are used in combination with variable-length compressionto improve compressibility in the cache/memory/data transferring subsystem in a computer system or in a communication network. 方法、设备和系统使压缩器和解压缩器扩展以用于对计算机系统的缓存/存储器/数据传输子系统中的或通信网络中的数据进行编码和解码。示例可变长度压缩器和解压缩器被扩展为具有新的特征以：当特定值在数据块中的
