Explanation:
FP - [tex]50 \times 10^6[/tex]
CPI - 1
INT -[tex]110 \times 10^6[/tex],
CPI - 1
I/S - [tex]80 \times 10^6[/tex] ,
CPI - 4
Branch - [tex]16 \times 10^6[/tex]
CPI - 2
Clock Speed - [tex]2 \times 10^9[/tex]
Time(old) =[tex]\frac{50 x 10^6 + 110 x 10^6 + 4 x ( 80 x 10^6) + 2 x (16 x 10^ 6)}{2 x 10^9}[/tex]
Time(old) = [tex]256 \times 10^ {-3}[/tex]
Time(new) = [tex]\frac{256 \times 10^{-3}}{2}[/tex]
= [tex]128 \times 10^{-3}[/tex]
=[tex]\frac{CPI(new) x [50 x 10^6 + 110 x 10^6 + 4 x ( 80 x 10^6) + 2 x (16 x 10^ 6)]}{2 x 10^9}[/tex]
= [tex]128 \times 10^{-3}[/tex]
CPI(new) = [tex]\frac{-206}{50}[/tex]
= -4.12
