標題[問題] OS-effective acces time 計算..
時間Tue Mar 31 02:21:35 2009
The memory access tiem is 15ns. But if page fault occurs, the time
becomes 10ms. If we want the effective access time not over 25ns,
what is teh maximum page fault rate?
(1ms=10^-3 , 1ns=10^-9)
洪逸是寫 15*(1-p)+p*10 *10^6ns ≦ 25ns
不太清楚那個10^6怎麼來的...印像中好像有看不同的答案
謝謝了
