a$.$ A processor has to execute a program with the following instructions mix: The average clock cycles per instruction

$1\mathrm{.}0375$

correct to $2$ decimal places. b$.$ A designer wants to improve the performance of this processor so he designs a new execution unit with the following adjustments: $-80\%$ of ALU operations take only $1$ cycle to execute and the other $20\%$ still take $2$ cycles to execute. $-95\%$ of the load instructions take only $2$ cycles to execute, while the remaining $5\%$ take $10$ cycles to execute. $-$ A store instruction takes $2$ cycles to execute. Compute the new average cycles per instruction $-$ Branches remain the same The average CPI for this new processor is correct to $2$ decimal places. c$.$ Assuming clock rate and instruction count remains unchanged, what is the speedup factor by which the performance has improved based on the adjusted CPI $($correct to $2$ decimal places$)?$
