Let us assume a program requires the execution of 50 million floating-point instructions and 100 million Integer instructions. The average number of clock cycles per instruction for each type of instruction is 2, and 1 respectively. The processor has a 1 GHz clock rate. a. What is the number of clock cycles for the above program? b. What is the execution time for the above program? c. By how much must we improve the CPI of the floating-point instructions if we want the program to run two times faster? d. By how much must we improve the CPI of integer instructions if we want the program to run two times faster?
