TLB Access time

Problem #1 (10 pts) Consider a paging system with the page table stored in memory. The system also has a TLB with 80% hit-rate. TLB-misses are handled by a separate co-processor, which always need an overhead of 20ns If a memory access takes 200 nanoseconds, how long does a paged memory reference take? (5 pts) Compute the effective access time of this system (5 pts) 1) 2)
