II. (a) An OS is using two-level paging to implement a 28-bit virtual address space per process. The page size is 256-bytes, and the machine does not have a TLB. Explain the steps involved in looking up the virtual address 0x03bf04d, when all pages are present in memory. (2 points) (b) For the system above, what is the maximum number of page faults that could be generated in response to a memory access? (2 points)

Virtual memory address translation: a) Consider a machine with a physical memory of 8 GB, a page size of 4 KB, and a page table entry size of 4 bytes. How many levels of page tables would be required to map a 52-bit virtual address space if every page table fits into a single page? b) Without a cache or TLB, how many memory operations are required to read or write a page in physical memory? c) How much physical...
