Consider a paging system where translation lookaside buffer (TLB) a special type of associative memory is used with hit ratio of 80%
Assume that memory reference takes 80 nanoseconds and reference time to TLB is 20 nanoseconds. What will be the effective memory access time given 80% hit ratio?

    Tavg = TLB access time + miss ratio of TLB × main memory access time + main memory access time
                = 20 + 0.2 &...
