Repeat Exercise 5.10.1, but this time use 16 KB pages instead of 4 KB pages. What would be some of the advantages of having a larger page size? What are some of the disadvantages?

Exercise 5.10.1

Given the address stream in the table, and the initial TLB and page table states shown above, show the final state of the system. Also list for each reference if it is a hit in the TLB, a hit in the page table, or a page fault.

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 table is a stream of virtual addresses as seen on a system. Assume 4 KB pages, a 4-entry fully associative TLB, and true LRU replacement. If pages must be brought in from disk, increment the next largest page number.

a. 4669, 2227, 13916, 34587, 48870, 12608, 49225 b. 12948, 49419, 46814, 13975, 40004, 12707, 52236 TLB Valid 1 1 1 0 Tag 11 7 3 st 4 Physical Page Number 12 4 6 9
