Answer:
CPI = 0.94
Explanation:
The formula for execution time is given below:
Execution time = clock cycles * cycle time
As Execution time = 750 s
clock cycle time = 0.333 ns = 0.333 * 10^-9
so putting these values in the above formula, we get
750 = clock cycles * ( 0.333 * 10^-9 )
clock cycles = 750 / ( 0.333 * 10^-9 )
clock cycles = 2.25 * 10^12
As the results of the spec cpu2006 bzip2 benchmark running on an amd barcelona has an instruction count = 2.389 * 10^12
and the formula for clock cycles is:
clock cycles = number of instructions * CPI
CPI = clock cycles / number of instructions
CPI = 2.25 * 10^12 / 2.389 * 10^12
CPI = 0.94
