5.16 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 four- entry fully associative TLB, and true LRU replacement. If pages must be brought in from disk, increment the next largest page number Decima14669 2227 13916 34587 488701260849225 hex 0x3140 0xc049 TLB Physical Page Time Since Last Valid Oxb 0x7 0x3 0x4 12 Page table Index Valid Physical Page or in Disk Disk Disk Disk Disk Disk 8 12
