Suppose that a system has 32-bit physical addresses, 48-bit virtual addresses and page size is 8KB. Let us also assume that accessing a page directly from main memory takes 100ns, while having to retrieve the page from the disk takes 2ms. 

requirement

a) What is the maximum required page fault rate in order to ensure average memory access time does not increase more than 25% of the direct memory access time?

 b) A Translation Lookaside Buffer (TLB) is added to the system. In case of a TLB hit, memory access is reduced to 30ns. The TLB hit rate is 95%. What is the average access time if we assume a page fault rate of 0.005%?
