A computer executes a benchmark which has 25 x 106 INT instructions, 55 x 106 FP instructions, 40 x 106 L/S instructions and 10 x 106 Branch instructions. The CPI for each type of instruction is 4, 16, 12, and 8, respectively. Assume that the processor has a 2 GHz clock rate. If the program has to run two times faster with the same clock rate, by how much must the CPI of FP instructions be improved?
