Summary:PURPOSE:To avoid the overhead of an address conversion buffer mechanism by accessing an address array and a buffer storage device by a physical address obtained by the previous address conversion. CONSTITUTION:A buffer storage device (BS) address, and an address array (AA) are constituted of a physical address 27 read out of a displacement field 26 and an address conversion buffer mechanism (TLB) 21. In such a state, the overhead of the TLB 21 is avoided by accessing the AA 22 and the BS 23 by the physical address obtained by the previous address conversion without accessing them by the physical address 27 read out of the TLB 21. In such a way, the overhead of the address conversion buffer mechanism to an access time of a buffer storage device can be avoided.
