VQ$2.$ Consider the following two processors. P$1$ has a clock rate of $4$ GHz$,$ average CPI of $0\mathrm{.}9,$ and requires the

execution of $5\mathrm{.}0$E$9$ instructions. P$2$ has a clock rate of $3$ GHz$,$ an average CPI of $0\mathrm{.}75,$ and requires the execution

of $1\mathrm{.}0$E$9$ instructions

a$.$ One usual fallacy is to consider the computer with the largest clock rate as having the largest performance.

Check if this is true for P$1$ and P$2$ by comparing their performance.

b$.$ Consider that processor P$1$ is executing a sequence of $1\mathrm{.}0$E$9$ instructions and that the CPI of processors P$1$ and

P$2$ do not change, determine the number of instructions that P$2$ can execute in the same time that P$1$ needs to

execute $1\mathrm{.}0$E$9$ instructions

A common fallacy is to use MIPS $($millions of instructions per second$)$ to compare the performance of two

different processors, and consider that the processor with the largest MIPS has the largest performance. Check if

this is true for P$1$ and P$2.$ Hint: A higher MIPS does not necessarily mean a better performance. Compare which

processor has higher MIPS, and relate this to the performance conclusion in part a$.$Q$2.$ Consider the following two processors. P$1$ has a clock rate of $4$ GHz$,$ average CPI of $0\mathrm{.}9,$ and requires the
