TLB lookup time (th) = 20 ns

TLB hit ratio (ht) = 99%

Memory access time (ts) = 100 ns

Page fault rate (hp) =0.05

Swap page time (in or out) (tp) = 5000,000 ns

What is the effective access time (EAT) if we assume that all pages currently in main memory are dirty?

  • 5118.91 ns

  • 51.21 ns

  • 5121ns

  • None of the above

Is the answer 5121 ?
