PURPOSE:To prevent a concentration of access frequency, and to elevate an efficiency of a memory access, by replacing an address bit from an access device, in a memory control device for controlling the access from a data processing equipment. CONSTITUTION:In accordance with access address information 51 from an access device of a data processing equipment, V bits showing an effective module of address converting information in register files MLINO, MUN1 are checked by a checking circuit 53, and if at least one of them shows effective ''1'', a part of a memory module number MN of the address information is replaced with an address in the module, and it is sent out to a memory unit. In case when all other bits except one show invalid ''0'', the access address information is not replaced but is sent out to the memory unit. |
