Compilers can have a profound impact on the performance of an application. Assume that for a program, compiler A results in an instruction count of 1.0E9 and has an execution time of 1.1s, and compiler B results in an instruction count of 1.2E9 and 1.5s
a. Find the average CPI for both compilers assuming a clock cycle time of 1ns.
b. Another Compiler C creates for the same code on 6.0E8 instructions, and has an average CPI of 1.1. What is the Speedup of the program using Compiler C vs Compiler A, and the Speedup of Compiler C vs. Compiler B, assuming in all cases the same clock cycle time of 1ns?

You look at compilers as a way to improve performance. Your outdated compiler produces an instruction count of 2 times 10^9 instructions which execute in 1.3 sec. a) What is the average CPI of the program if the clock period is 0.5 ns? b) A new compiler generates only 1 times 10^9 instructions, with a CPI of 1.2. On the same processor (same clock), what speedup does the new compiler produce?

I need help with the following Computer Architecture question: Consider two different implementations, M1 and M2, of the same instruction set. There are three classes of instructions (A, B, and C) in the instruction set. M1 has a clock rate of 90 MHz and M2 has a clock rate of 80 MHz. The average number of cycles for each instruction class and their frequencies (for a typical program) are as follows: Instruction Class Machine M1 – Cycles/Instruction Class Machine M2...
