Question

For each access shown above, list:

  1. Whether the access is a hit or miss in the TLB
  2. Whether the access is a hit or miss in the page table
  3. Whether the access is a page fault
  4. The updated state of the TLB

 

Note, you need to answer the above questions in the table below. The time since last access shows the MRU (most recently used) to LRU (least recently used) positions in the fully-associative TLB with true LRU replacement. The time is set to ‘0’ upon a hit to a page or a new page is entering the TLB. The rest of the times in TLB are incremented by 1 to maintain proper MRU to LRU order.

This exercise shows how this 482 Chapter 5 Large and Fast: Exploiting Memory Hierarchy 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.
