Th e results of the SPEC CPU2006 bzip2 benchmark running on an AMD Barcelona has an instruction count of 2.389E12, an execution time of 750 s, and a reference time of 9650 s. Find the CPI if the clock cycle time is 0.333 ns.

Answer:

CPI = 0.9425

Explanation:

Given data:

instrument count = 2.389E12

Execution time = 750 s

refrence time = 9650 s

we know that CPU time can be calculated as

[tex]CPU\ time  =  instruction\ count \times CPI\times\ clock\ cycle time[/tex]

CPU time sometime knows as execution time

so

[tex]Execution\ time = instruction\ time \times CPI \times clock\ cycle\ time[/tex]

For clock cycle time [tex]0.33 ns = 0.33 \times 10^{-9} s[/tex]

[tex]CPI =  \frac{Execution\ time}{intruction\ time \times clock\ cycle\ time}[/tex]

[tex]CPI = \frac{750}{2.389E12 \times 0.33\times 10^{-9}}[/tex]

CPI = 0.9425
