Suppose that new, more powerful arithmetic instructions are added to the instruction set. On average, through the use of these more powerful arithmetic instructions, we can reduce the number of arithmetic instructions needed to execute a program by 25%, and the cost of increasing the clock cycle time by only 10%. Is this a good design choice? Why?

The CPI of the different instruction types is given in the following table. a. b. Arithmetic 1 4 Load/Store 10 40 Branch 3 3
