Consider the two computers A and B with the clock cycle times 100 ps and 150 ps respectively for some program. The number of cycles per instruction (CPI) for A and B are 2.0 and 1.0 respectively for the same program. Which computer is faster and how much? a) A is 1.33 times faster than B b) B is 1.22 times faster than A c) A is 1.23 times faster than B d) B is 1.33 times faster than A
