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...

3. Consider a paging system with the page table in memory. A. If a memory reference takes 100 nanoseconds, how long does a paged memory reference take? B. If we add TLBs, and 75 percent of all page-table references are found in the TLBs, what is the effective memory reference time? (Assume that finding a page-table entry for the TLBs takes 20 nanoseconds.) C. It takes 750 milliseconds to service a page fault. The page fault rate is .001. What...

Please answer the following questions about paged memory... A) How much space needs to be allocated in the minimum and maximum cases for a two-level page table for a machine with a 32-bit virtual memory address, a 1K page size, and which has four times as many inner pages as outer pages? Assume any stored page table value requires 32 bits. B) For the two-level paging approach above, if a Translation Lookaside Buffer (TLB) is used and can cache both...
