Apitfall cited in section 1.10 is expecting to improve the overall performance of a computer by improving only one aspect of the computer. consider a computer running a program that requires 250 s, with 70 s spent executing fp instructions, 85 s executed l/s instructions and 40 s spent executing branch instructions(5 min, sec 1.10)by how much is the total time reduced if the time for fp operations is reduced by 20%? (5 min, sec 1.10) by how much is the time for int operations reduced if the total time is reduced by 20%? (5 min, sec 1.10) can the total time be reduced by 20% by reducing only the time for branch instructions?
