Question $2$

$4$ pts

Compilers can have a profound impact on the performance of an application. Assume that for a program, compiler A results in a dynamic instruction count of $1\mathrm{.}0$E$9($which is $1\mathrm{.}0**10)$ and has an execution time of $1\mathrm{.}1s,$ while compiler $B$ results in a dynamic instruction count of $1\mathrm{.}2E9($which is $1\mathrm{.}2**{10}^9)$ and an execution time of $1\mathrm{.}5s.$

Question: Select two answers for each program compiled using compiler A and compiler B given that the processor has a clock cycle of $1ns.$

CPI of the program compiled with the compiler $B$ is $2\mathrm{.}1.$

CPI of the program compiled with the compiler $B$ is $1\mathrm{.}25.$

CPI of the program compiled with the compiler $A$ is $1\mathrm{.}1.$

CPI of the program compiled with the compiler $A$ is $1\mathrm{.}5.$

CPI of the program compiled with the compiler $A$ is $1\mathrm{.}0.$

CPI of the program compiled with the compiler $B$ is $1\mathrm{.}67.$
