Abstract
A processor includes a page table walk cache that stores address translation information, and a page table walker. The page table walker fetches first output addresses indicated by first indexes of a first input address by looking up the address translation information and at least a part of page tables, and compares a matching level between second indexes of a second input address and the first indexes of the first input address with a walk cache hit level obtained by looking up the page table walk cache using the second indexes.
