(12pts ) 3. A Processor chip is used for applications, in which: 40% time is usded for floating point addition; 24% time is used for floating point multiplication; 10% time is used for floating point division. A new model of such processor has 3 possible enhancements, cost roughly the same, which one (A, B, or C) should be chosen, please explain the reason? A. redesign the floating-point adder to make it twice as fast. B. redesign the floating-point multiplier to make it 3 times as fast C. redesign the floating-point divider to make it 10 times as fast
