Problem 6 (20 pts) 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 constitutes a stream of virtual addresses as seen on a system. Assume 4 KiB pages, a 4-entry fully associative TLB, and true LRU replacement (the larger LRU tag indicates less recently used). If pages must be brought in from disk, increment the next largest page number. 7843, 1998. 16744, 13344, 53233, 33214, 55167 TLB Valid Tag LRU Tag Physical Page Number 12 4 4 4 2 Problem 6 (20 pts) Virtual memory uses a page table to track the mapping of virtual addresses to physical addresses.
