0.99(20 + 0.9995*100 + 0.0005*5000000) + 0.01(20 + 100 + 0.9995*100 + 0.0005*5000000) = 2620.5ns

effective memory access time
A demand paging uses a TLB and a single level page table stored in main memory. The memory access time is 5s. The page fault service time is 25s. If 70% of access is in TLB and of the remaining, 20% is not present in the main memory. The effective memory access time is? Thanks!

Effective memory access time
What has to be the general and final formula for calculating the effective memory access time, taking in consideration the $\alpha$-level page table, TLB hit ratio as $h$, miss ratio as $m$, memory access time as $M$ ... for page fault servicing as $x$? There seems to be so many formulae, each different from each other depending on the question.

Computing Effective Memory access time - Cache organization
Consider the following information about a hypothetical processor. Assume the cache is physically addressed TLBHit Rate: 95% access time 1 cycle Cache Hit Rate: 90% access time 1 cycle when tlb and cache both get miss, page fault rate 1% TLB access and ... 1 + .1(5+ .01(100) ) = 2.675 Could someone pls point out the flaw in the logic?
