Version A has a dynamic instruction count of 2.0 x 109 and an execution time of 4 seconds, while version B has a dynamic instruction count of 2.5 x 109 and an execution time of 6 seconds. (a). Find the CPIs for the two executables (Version A and Version B) respectively given that machine M has a frequency of 2GHz (i.e. 2x109 Hz). (b).
