A system implements a paged virtual address space for each process using a one-level page table. The maximum size of virtual address space is 8MB. The page table for the running process includes the following valid entries (the -> notation indicates that a virtual page maps to the givenpage frame, that is, it is located in that frame): Virtual page 2 -> Page frame4 Virtual page 4 -> Page frame 9 Virtual page 1 -> Page frame2 Virtual page 3...

1) Given a virtual memory system with: virtual address 36 bits physical address 32 bits 32KB pages (15 bit page offset) Each page table entry has bits for valid, execute, read and dirty (4 bits total) and bits for a physical page number. a) How many bits in the page table? (do not answer in bytes!) Three digit accuracy is good enough. The exponent may be either a power of 2 or a power of 10. b) The virtual address...

A computer system has a 36-bit virtual address space with a page size of 8K, and 4 bytes per page table entry. How many pages are in the virtual address space? What is the maximum size of addressable physical memory in this system? If the average process size is 8GB, would you use a one-level, two-level, or three-level page table? Why? Compute the average size of a page table in part c above
