COMPUTER ARCHITECTURE- Q3. Suppose that we have two implementations of the same instruction set architecture: Machine A has a clock cycle time of 12 ns and a CPI of 2.25 for some program. Machine B has a clock cycle of 22 ns and a CPI of 1.75 for the same program. 1. Find the CPU time for each machine? . ● 2. Which machine is faster? by how much? Q4: A compiler designer is trying to decide between two code sequences for a particular machine. For a particular high-level language, the compiler writer is considering two sequences that require the following instruction counts: (2 points) Instruction counts (in millions) Code 1 CPI of the instruction class Instruction class Code 2 2 1 2 A B C 1. What is the CPI for code 1? 2. What is the CPI for code 2? 3. Which code is faster? Why? 2 3 A B C 4 CPI of the instruction class 1 2 3 1. Which code sequence will execute faster according to MIPS? Why? 1 1 Q5: Consider a machine with three instruction classes. Suppose that we measured the code for a given program in two different compilers and obtained the following data (Assume that the machine's clock rate is 150 MHz.): (2 points) Instruction class (2 points) Instruction counts (in millions) Compiler 1 Compiler 2 10 5 1 1 1 1 2. Which code sequence will execute faster according to execution time? Why?
