To calculate EMAT in case of page fault we used:
EMAT= page fault rate*(page fault service time) + (1-page fault rate)*(memory access time)
My doubt is:
In case of NO PAGE FAULT, why we considered only one memory access time .
Why not two memory accesses, one for page table + one for accessing actual byte. ?
That is:
Why not this formula:
EMAT= page fault rate*(page fault service time) + (1-page fault rate)* (2 * memory access time)

Here, in TLB + Page Fault type question,
You considered (VA -> PA time) + memory access time.
Then why not we consider address translation time in questions involving only pagefault?
