<p>An information processing apparatus 10 includes a cache device 500 containing a cache memory 560 formed from at least one hierarchy, and small (µTLB 530) and large (µTLB 540) conversion tables. A pre-fetch command speculatively transfers data or a command from a main storage 30 to the cache memory. A cache controller 510 provides control to execute the pre-fetch command in such a way that a virtual address is converted to a physical address using the first conversion table, the virtual address and the physical address being stored as a pair if the conversion succeeds, while if not the entry is written from the large table to the small table.
