Chapter 1, Problem 1.11.9E

Explanation of Solution

The number of instructions can be calculated using the following formula

$\text{Number}\text{of}\text{instructions}\text{=}\frac{\text{CPU}\text{time}\text{×}\text{clock}\text{rate}}{\text{CPI}}$

Substitute, “$\text{960}\text{×}\text{0}\text{.9}$” for “CPU time”, “$\text{4}\text{×}{\text{10}}^{\text{9}}$” for “clock rate” and “1.61” for “CPI” in the above formula

$\begin{array}{c}\text{Number}\text{of}\text{instructions}\text{=}\frac{\text{960}\text{×}\text{0}}{}\end{array}$
