please help 04 please help 04 4. Consider a main memory access time of 32ns.

4. Consider a main memory access time of 32ns. A. If we used a two-layered paging system, how long would it take to convert a virtual address and access the memory location? B. Let's add a really fast cache of 4 ns that caches the frame number for a virtual page. What would be the average access time for the meory if the cache hit rate were 91% ? Remember that you still have to go to the actual frame to get the data! C. What cache hit rate would we need if we wanted the average time to be 60 ns? Again, remember that the actual data/code memory access of 32ns is included in this figure. Hint: This is an algebra problem. Plug what you have into the formula and solve for what you don't have
