Suppose on-demand paging is employed in addition to TLB caching. The time for a TLB hit is T= 1 ns, a memory read M = 10 ns, and a disk read D = 10 ms. Let P_TLB = 90% the probability of a TLB hit, and P = 0.001 the probability of a page fault given a TLB miss. What is the probability of a TLB miss? What is the probability of a NO page fault? what is the calculated average memory access time in Nano seconds (up to 3 decimal places)?
