PURPOSE:To reduce the time required for repealing process of an address conversion pair, by repealing all address converting information within a block with the repealing control information held by a piece of address converting information of an address converting buffer. CONSTITUTION:An address converting buffer ATB20 is divided into blocks 21-24 in accordance with the divided segments of a virtual memory. The address converting information concerning each segment of the virtual memory is stored in the corresponding blocks 21-24. If the repealing is indicated for an address conversion pair on the ATB20 and, for instance, if the state of the SSI bit stored in a latch 31 is ''0'', the V bits of all entries 201-204 within the block 21 are reset to repeal the address conversion pair of the block 21. |
