Given that, in a virtual memory system, if the probability of a page fault is p, the mainmemory access time is tm and the time required to move a secondary page into the main memory is ts , derive an expression for the average access time ta.

Solution

Expression:

average access time =hit* main memory access time + miss*secondary memory access time

So,

ta = (1-p) * tm + p * ts is the desired expression
