Question: A portion of the currently running process's page table is shown below: Virtual page # Reference Valid bit Dirty bit Frame # bit 7

A portion of the currently running process's page table is shown below: Virtual page # Reference Valid bit Dirty bit Frame # bit 7 1 1 1 3 8 0 0 0 9 1 0 1 -- 4 10 0 0 11 12 1 1 1 1 0 0 - 0 0 1 Assume the system uses 20-bit addresses and 16 KB pages. The process accesses four addresses: Ox25FEE, 0x2B149, 0x30ABC, and Ox3170F. Determine (i) which address would cause a page to be evicted if there were no free physical frames, (ii) which one would mark a previously clean page as modified, if the access were a write, and (iii) which one accesses a page that has not been referenced for many cycles. For full credit, show all work.
