ABSTRACT:
For handling data having a fixed-order context, a data compression system uses a pipeline control unit to enable an occurrence frequency modeling unit and entropy coding unit to operate in pipelining. A data restoration system uses a pipeline control unit to enable an entropy decoding unit and occurrence frequency modeling unit to operate in pipelining. For handling data having a blend context, occurrence frequency modeling units associated with orders are operated in parallel for data compression or data restoration. Furthermore, word data is separated byte by byte, and byte data items are encoded or restored on the basis of the correlation thereof in a word-stream direction.
