Explain how to find the physical memory address from the logical address, and give an example to calculate the memory address.

(30 extra points) The following sequence is a stream of virtual addresses computed by the processor. Assume that page size is 16KiB and the system has a 4-entry fully associative TLB which uses true LRU replacement policy when needed. Given that the following tables show the initial state of the page table and TLB, answer the following questions. 55324, 19232, 40235, 1012, 48020, 20116, 88124, 36192, 20196, 424 Table 1: Initial content of TLB (left) and page table (right). Valid | Tag (vpn) | Phys. Page No. (ppn) 1 | 5 | 2 0 | 1 | 2 1 | 2 | 1 1 | 1 | 5 Valid | Physical Page or Disk 0 | Disk 1 | 5 1 | 1 1 | 4 0 | Disk 1 | 2 (a) (15 points) Specify the references that cause TLB hit, TLB miss, and Page Fault. Also, write the final status of both TLB and page table. If a page must be swapped in from disk, place it in the next largest page number. (b) (15 points) Translate each virtual address and find its corresponding physical address.
