PURPOSE:To reduce the overhead for inter-processor communication and data relaying, by transferring data to a cell of the access request source if desired data exists in the cache memory on a cell which the data access request passes. CONSTITUTION:Each cell 2-1 is provided with a cache memory 5-i in which data which at least this cell itself requires or data transferred through this cell on demand is held; and if desired data exists on a cache memory 5-k of a cell 2-k which the data access request from a certain cell passes, this data is transferred to the cell which issues the data access request. Thus, the overhead for inter-processor communication in case of data access to another cell or the overhead for data relaying is reduced. |
