Problem 1 (Amdahl's Law, Chapter 1) Assume a program requires the execution of 150x10$ floating-point instructions, 100x106 integer instructions, 70x10 load/store instructions and 25x10% branch instructions. The CPI for each type of instruction is 3, 1, 6, 2, respectively. Assume that the processor has a 1 GHz clock rate. A. By how much must we improve the CPI for floating-point instructions if we want the program to run 1.25 times faster? B. By how much is execution time of the program improved if the CPI for integer and floating-point instructions is reduced by 25%, and the CPI of the load/store and the branch instructions is reduced by 20%
