Suppose that when a certain processor is run on an intense mathematical benchmark, 50% of the instructions are floating-point instruction, including 10% which compute a square root (i.e. 40% of the instructions are floating-point instructions that do not computer square root). Assume that the floating-point square root instruction has an average CPI of 10, the other floating-point instructions (not including the
square root instruction) have an average CPI of 3, and the average CPI of non-floating-point instructions is 1.5.
