As described in Section 5.7, virtual memory uses a page table to track the mapping of virtual addresses to physical addresses. This exercise shows how this table must be updated as addresses are accessed. The following data constitute a stream of virtual byte addresses as seen on a system. Assume 4 KiB pages, a fourentry fully associative TLB, and true LRU replacement. If pages must be brought in from disk, increment the next largest page number. Decimal 4669 hex |2227 |13916 34587 |48870 | 12608 |49225 | Ox123d |0x08b3 0x365c 0x871b| 0xbee6 | 0x3140 |Oxc049 | TLB Physical Page Number Time Since Last Valid Tag Access 12 Ox7 4 Ox3 On4 Page table Physical Page or ln Disk Index Vald Disk Disk 4. 11 Disk Disk Disk 12 [10] <§5.7> For each access shown above, list • whether the access is a hit or miss in the TLB, • whether the access is a hit or miss in the page table, • whether the access is a page fault, • the updated state of the TLB.
