1.7 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 Bresults in a dynamic instruction count of 1.2E9 and an execution time of 1.5 s. 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 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?
Computer A has an overall CPI of 1.3 and can be run at a clock rate of 600MHz. Computer B has a CPI of 2.5 and can be run at a clock rate of 750 MHz. We have a particular program we wish to run. When compiled for computer A, this program has exactly 100,000 instructions. How many instructions would the program need to have when compiled for Computer B, in order for the two computers to have exactly the same execution time for this program? Please explain how to solve
