1.7 [15] < §1.6> compilers can have a profound impact on the performance of an application. assume that for a program, compiler a results in a dynamic instruction count of 1.0e9 and has an execution time of 1.1 s, while compiler b results in a dynamic instruction count of 1.2e9 and an execution time of 1.5 s.(a) find the average cpi for each program given that the processor has a clock cycletime of 1 ns.(b) assume the compiled programs run on two different processors. if the executiontimes on the two processors are the same, how much faster is the clock of theprocessor running compiler a’s code versus the clock of the processor runningcompiler b’s code?
