Assume that we have an application with a total of 500,000 instructions where 20% of them are the load/store instructions with a

n average CPI of 6 cycles, and the rest instructions are ALU instructions with average CPI of 1 cycle. If we double the clock rate without optimizing the memory latency, the average CPI for load/store instruction will also be doubled to 12 cycles. What is the speedup after this change?

Answer:

1.25

Explanation:

#instructions = 5*10^{5}  

Average CPI (old) = 0.2*6 + 0.8*1 = 1.2+0.8 = 2.0

Average CPI (new) = 0.2*12 + 0.8*1 = 2.4 + 0.8 = 3.2

Assuming Clock Rate = x

Speedup = Execution Time (old) / Execution time (new)  = (2.0*5*10^{5} /x) / (3.2*5*10^{5} /2x)  = 4/3.2 = 1.25

1 or 2 ways I can try to figure out and see what is causing your computer to do this. 1 when was the last time you shut off  OR was doing on the computer? If your problem gets fixed make sure you close all running apps so the apps don't update while your computer is shutdown. 2 did you or something unplug the cables? Or maybe a virus caused something. Try to unplug every cable and wait about 5-10 minutes and if your computer is still not working, I would advise contacting an administrator.

Hope this helped.
