insinuctions take $6$ cycles and integer instructions take $2$ cycle. How long does it for this processor to run the program? And calculate the average CPI

$3$

b$)$ Which of the following improvement options in the processor will take lesser time to execute the program If $($a$)$ the CPI of floating porit instruction is reduced to $4$ and the integer takes the same time as the base or $($b$))$ the CPI of integer is reduced to $1$ and the flosting aoint instruction takes the same time as the base. How much faster is the improved machine compared to the base machine?

$2+2$
