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.

    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
