An arithmetic processing apparatus includes a main TLB that stores therein, as a page table, entries indicating correspondences between virtual and physical addresses, and a micro TLB that stores therein part of the table. The apparatus associates together the physical address stored in the main TLB, the virtual address associated with the physical address, and a context ID included in an address-translation request and registers these associated together in the micro TLB as an entry. When receiving the request, the apparatus does not translate the context ID included in the request into a context value but searches for an entry matching the virtual address and the context ID included in the request. When the entry is searched for and found, the response is the physical address included in the entry. When the entry is searched for and not found, the request is transmitted to the main TLB.
