ABSTRACT:
In an information processing apparatus (10) that includes a cache memory (560) formed from at least one hierarchy, and a pre-fetch command that 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 such that a virtual address is converted to a physical address using a conversion table, and the virtual address and the physical address are stored as a pair if the conversion succeeds.
