Question

Consider a pagination-based system where sheettables are stored in the main memory:a. If a normal memory access to a memory cell takes 50 nanoseconds, how long does a paged memory access take?b. In the scenario where we add a TLB to the system and 75 percent of all page table references are in TLBs, what is the effective memory reference time? (Assume that it takes 2 nanoseconds to find the row corresponding to a page table in the TLB if it is available in the TLB).
