computer architecture求大神.
This question requires you to generalize Amdahl’slaw to the case when multiple enhancements are possible.Three enhancementswith the following speedups are proposed for a new architecture:
Speedup1=20,Speedup2= 10,Speedup3 = 5.
Only one enhancement is usable at a time (butmultiple can be used over the entire application).If enhancements 1 and 2 areeach usable for 25% of the time,what fraction of the time must enhancement 3be used to achieve an overall speedup of 10 for the entire application?

Speedup= 1 / [1 - ∑i FEi + ∑i FEi/SEi ]
Speedup= 1 / [1 – (FE1+FE2+FE3) + (FE1/SE1) + (FE2/SE2) + (FE3/SE3)]
10 = 1/ [1 – (0.25+0.25+FE3) + (0.25/20) + (0.25/10) + (FE3/5)]
FE3 = 54.6875%
这样的话 FE1 + FE2 + FE3 > 100%
你的条件是不是给错了
