Question 1 4 pts The performance of a computer system with 1 microprocessor is measured. What affect would replacing the microprocessor with a slower model have on the performance of the system? Response Time decreases. Throughput increases Response Time increases. Throughput decreases Response Time remains the same, Throughput increases Response Time decreases. Throughput remains the same Question 2 4 pts While the use of a pipeline can improve performance, why might longer pipelines degrade performance? Longer pipelines always result in worse performance compared to shorter pipelines. A longer pipeline means each instruction must be broken into a larger number of stages. As a result, the microprocessor spends more time loading instuctions into the pipeline rather than actually execute instructions. Fewer pipeline stages improves performance. Longer pipelines always result in better performance compared to shorter pipelines. If the microprocessor predicts and loads the wrong set of instructions into the pipeline, it will take longer to clear out a longer pipeline, load the correct set of instructions, and begin executing instructions again than a shorter pipeline. Question 3 4 pts Which 2 instructions can be executed in parallel? Both of the answers are correct None of the answers are correct int a = 2* int b = 4 - a; O int x = 4/b; int y = b -2
