A compiler designer is trying to decide between two code sequences for a particular machine. Based on the hardware implementation, there are three different classes of instructions: Class A, Class B, and Class C, and they require one, two, and three cycles (respectively) The first code sequence has 4 instructions: 2 of A,1 of B, and 1 of C The second sequence has 5 instructions: 3 of A,1 of B, and 1 of C Find out following questions: Which sequence will be faster? How much? What is the CPI for each sequence
