Question #1)

Question 2 & Question 3)

Please answer Question 1 and if you can't answer Question 2& Question 3 thats fine

but answer question 1 entirely

We were introduced to five different techniques built into modern processors to improve performance. Which of the following attributes below apply to each of the techniques? Characteristic 1. Mav run instructions that are not needed 2. Prefetches instructions 3. Restricts each stage to the speed of the slowest 4. Allows two instructions in the same pipeline stage 5. Reduces cycles spent 6. Allows multiple instructions to run simultaneousl 7. Searches for dependencies between instructions 8. Duplicates some components of a pipeline to create in effect ogram on average multiple parallel pipelines 9. CPU looks ahead to guess which branches will be taken 10. Runs instructions ahead of time 11. Combining multiple instructions in a single pipeline 12. Stores results in intermediate locations 13. Divides the CPU into multiple stages 14. Multicore designs essentially mimic this technique that existed on single-CPU designs 15. Often records past results of logical tests to make decisions on what to fetch next 16. May have to flush instructions out of the pipeline mid execution but before results are committed 17. Runs instructions out-of-order 18. Doesn't just study/manipulate instructions, this technique(s) 19. Improves efficiency of the execution of programs 20. Incre actually initiates their execution ases CPI on average
