Problem #4 Compilers can have profound impact on the performance of an application. Assume that for a program, compiler A results in a dynamic instruction count (IC) of 10% and has an execution time to 1.1 s, while compiler B results in a dynamic instruction count (Cs) of 1.2x10% and has an execution time to 1.5 s. (i) Find the average CPI for each program given that the processor has a clock cycle time of 1 ns. Assume the compiled programs run on two different processors. If the execution times on the two processors are the same, how faster is the clock of the processor running compiler A's code versus the clock of the processor running compiler B's code? (i) (i) A new compiler is developed that uses only 6x10 instructions and has an average CPI of 1.1 What is the speedup of using this new compiler versus using compiler A or B on the original processor
