PURPOSE:To simplify an address conversion processing system and to attain high processing speed by using such a circuit that produces arithmetically an address from address higher bits. CONSTITUTION:In an address conversion mode an allocating area 23A is previously set to a real memory. Then an operation is carried out through an arithmetic circuit part 24A and a multiplication part 24B to perform the conversion of addresses. In such a way, an address space is controlled for each fixed small area and the address conversion is arithmetically carried out by the instruction of the area 23A.
