PURPOSE:To keep constant the hit rate of address conversion of each virtual space, by providing a mapping corresponding table from logical address to real address for independent TLB(translation look aside buffer) at each virtual space. CONSTITUTION:The conversion from the logical address to the real address under the virtual storage space under present processing is made by obtaining the correspondence table 3-i of the TLB of the virtual space with a space instruction pointer 1 indicating the virtual storage space under processing from the TLB3 being correspondence tables 3-1-3-n from the logical address and real address sectioned at each virtual storage space. This is the same as the processing of a single virtual storage space, and the upper part of the logical address 2 and the logical page address of each entry of the correspondence table 3 are compared at a comparison circuit 4 and the real address is produced with the coupling between the real page address in the coincident entry and the lower part of the logical address 2. |
