ADDRESS TRANSLATION INSPECTION DEVICE, CENTRAL PROCESSING DEVICE, AND ADDRESS TRANSLATION INSPECTION METHOD |
摘要 |
An information processing apparatus includes an MMU that translates between a virtual address and a physical address on the basis of a translation table for translation between physical addresses that are addresses in physical memory and virtual addresses that are addresses in virtual memory. Stored in a RAM are page table information indicating a page table, as well as error detection information attached to the page table information for detecting the presence or absence of an error in translation between a virtual address and a physical address performed by the MMU. A CPU detects the presence or absence of an error in translation between a virtual address and a physical address performed by the MMU on the basis of the error detection information. |
