ABSTRACT:
A method and apparatus for compressing a block of data using a shared dictionary. Data to be compressed is divided into subblocks which are each provided to a respective compressor in a plurality of compressors. The compressors cooperatively construct a dynamic compression dictionary and compress the subblocks in parallel using the dictionary. Compressed subblocks output by the compressors are concatenated to form a compressed block.
