Question

The 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 1

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
