PROBLEM TO BE SOLVED: To parallel perform a collation operation in compression and expansion and to perform efficient communication based on data compression between modules in a processor. SOLUTION: Data is compressed in a data transfer mode by using a memory and computing element integrated type parallel processor architecture for compressing and expanding data. Transmitting data is compressed in a compression module 3 of a module A1 and is transferred to a module B2. An expansion module 4 of a module B2 expands received data. In such a case, 'instantaneously decodable' algorithm, that is, such algorithm as to start to expand just after a module B receives data is used as compression algorithm. Then, it is possible to overlap expansion time 8 and transfer time 7. |
