[Qual-CA] - Chapter1 Problem

1.4.4 

 

2Ghz Process의 뜻은 -> ½ Execution Time이라고 보면된다.

 

Time = (650 x 1) + (100*5) + (600*5) + (50*2) * ½ * 10-9 

 

1.5.5

 

CPI = time * clock_rate ( 2 * 10^9 ) / No of Instructions  = 1.92

 

1.4.6.

 

500 x 1 + 50 x 5 + -> 550

 

Speed Up -> 650/550 ns

 

CPI = time * clock_rate / No of Instructions (700) 

 

이렇게 하면 될듯
