- Memory access time is 100 nano sec.
- Effective_memory_access is 107 nano sec (with TLB when TLB access is 5 nano sec).
- Page fault overhead is 100 micro sec.
- Page swap time is 10 millisecond.
- 50% of the time, the page that is being replaced has been modified and therefore needs to be swapped out.
- Restart overhead is 20 micro sec.
- p - page fault rate.
Effective Access Time = 107* (1-p) +( 100,000+ 10,000,000+0.5*10,000,000+20,000+5+200)*p
EAT = 107 *(1-p) + 15,120,205*p.
