In a multi cycle CPU, all instructions take 4 clock cycles per instruction, except the multiply instruction, which takes 12 clocks. If 10% of the instructions in most programs are multiply instructions;
a. What percentage time is spent by the CPU executing the multiply instruction?
b. The hardware engineer said that she could redesign to make the multiply instruction take 6 clocks instead of 12 clocks, provided the clock period may be increased b 20%, Shall we go for it? Please explain.
