Question: 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

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 is the EAT? Include the TLB hit and miss portions of the equation.
