Compilers can have profound impact on the performance of 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 cycle time of 1 ns b) Assume the complied programs run two different processors. If the execution times on the two processor are the same, how much faster is the clock of the processor running compiler A's code versus the clock of the processor running compiler B's code? c) A new compiler is developed that uses only 6.0E8 instructions and has an average CPl of 1.1. What is the speedup of using this new compiler versus using compiler A or B on the original processor
