Please help me with this digital computer system question, I will be grateful to you, thanks

Fall 2018 This assignment is due the beginning of the class at Sept.18. You can solve the assignment in a group of 2 students. 1. Consider three different processor P1, P2, and P3 executing the same instruction set P1 has a 3 GHz clock rate and a CPI of 1.5. P2 has a 2.5 GHz clock rate and a CPI a) Which processor has the highest performance expressed in instructions per If the processors each execute a program in 10 seconds, find the number of cycles c) We are trying to reduce the execution time by 30% but this leads to an increase of of 1.0. P3 has a 4.0 GHz clock rate and has a CPI of 2.2 second? b) and the number of instructions. 20% in the CPI. What clock rate should we have to get this time reduction? 2. 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 CPI of 1.1. What is the speedup of using this new compiler versus using compiler A or B on the original processor
