Dr$.$ Gang Quan$1/28/2024$Then voltage$\_$new $=9*9$V$=81$V this is needed to maintain the same leaking current$1\mathrm{.}15\mathrm{.}105.$ Assume for arithmetic, load store, and branch instructions, a processor has CPIs of $1,12,$ and $5,$ respectively. Also assume that on a single processor a program requires the execution of $2.56$E$9$ arithmetic instructions, $1\mathrm{.}28$E$9$ load$/$store instructions, and $256$ million branch instructions. Assume that each processor has a $2$ GHz clock frequency$-$Assume that, as the program is parallelized to run over multiple cores, the number of arithmetic and load$/$store instructions per processor $1$s divided by $0\mathrm{.}7$ x p $($where p is the number of processors$)$ but the number of branch instructions per processor remains the same.I. Find the total execution time for this program on $1,2,4,$ and $8$ processors, and show the relative speedup of the $2,4,$ and S processor result relative to the single processor result.$/$IL$.$If the CPI of the arithmetic instructions was doubled, what would the impact be on the execution time of the program on $1,2,4,$ or $8$ processors?Ill.To what should the CPI of load$/$store instructions be reduced in order for a single processor to match the performance of four processors using the original CPI values?
