METHODS, DEVICES AND SYSTEMS FOR EFFICIENT COMPRESSION AND DECOMPRESSION FOR HIGHER THROUGHPUT

摘要

A decompression system (800; 1100; 1300) for decompressing a compressed data block that comprises a plurality of compressed data values is presented. The decompression system has a plurality of decompression devices (700; 1200A-B) in an array or chain layout (820a-820m-1; 120a-1120m-1; 1320a-1320m-1) for decompressing respective compressed data values of the compressed data block. A first decompression device (820a; 1120a; 1320a) is connected to a next decompression device (820b; 1120b; 1320b), and a last decompression device (820m-1; 120m-1; 1320m-1) is connected to a preceding decompression device (820m-2; 1120m-2; 320m-2). The first decompression device (820a; 1120a; 1320a) decompresses a compressed data value of the compressed data block and reduces the compressed data block by extracting a codeword of the compressed data value and removing the compressed data value from the compressed data block, retrieving a decompressed data value out of the extracted codeword, and passing the reduced compressed data block to the next decompression device (820b; 1120b; 320b). The last decompression device (820m-1; 1120m-1; 1320m-1) receives a reduced compressed data block as reduced by the preceding decompression device (820m-2; 1120m-2; 320m-2) and decompresses another compressed data value of the compressed data block by extracting a codeword of said another compressed data value, and retrieving another decompressed data value out of the extracted codeword.
