This Question Covers Virtual Memory Access

question 21

Essay

This question covers virtual memory access. Assume a 5-bit virtual address and a memory system that uses 4 bytes per page. The physical memory has 16 bytes (four page frames). The page table used is a one-level scheme that can be found in memory at the PTBR location. Initially the table indicates that no virtual pages have been mapped. Implementing a LRU page replacement algorithm, show the contents of physical memory after the following virtual accesses: 10100, 01000, 00011, 01011, 01011,11111. Show the contents of memory and the page table information after each access successfully completes in figures that follow. Also indicate when a page fault occurs. Each page table entry (PTE) is 1 byte. This question covers virtual memory access. Assume a 5-bit virtual address and a memory system that uses 4 bytes per page.
