Assume that the page table can held in registers of the MMU. It takes 8 ms (milliseconds) to service a page fault if there is an empty frame or if the replaced page is not altered, and 20 ms if the replaced page is altered. Memory access time is 100 ns (nanoseconds). It has been empirically measured that the page to be replaced is altered 75% of the time. Obtain the maximum probability of page fault for an effective memory access time ≤ 200 ns.

Question

I am trying to better understand memory access in computers, please answer the sample question below.

Assume that the page table can held in registers of the MMU. It takes 8 ms (milliseconds)
to service a page fault if there is an empty frame or if the replaced page is not altered, and
20 ms if the replaced page is altered. Memory access time is 100 ns (nanoseconds).

It has been empirically measured that the page to be replaced is altered 75% of the time.
Obtain the maximum probability of page fault for an effective memory access time ≤ 200
ns.
