Store

300

Branch

100

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?
