An unpipelined processor takes 10 ns to work on one instruction. It then takes 0.2 ns to latch its results into latches. I was able to convert the circuits into 10 sequential pipeline stages. The stages have the following lengths: 1.3ns; 0.7ns; 0.8ns; 1.2ns; 0.7ns; 1.4ns; 0.7ns; 0.4ns; 1.5ns; 1.3ns. Answer the following, assuming that there are no stalls in the pipeline.
1.What are the cycle times in both processors?
2.What are the clock speeds in both processors?
3.What are the IPCs in both processors?
4.How long does it take to finish one instruction in both processors (in nano-seconds and cycles)?
5.What is the speedup provided by the 10-stage pipeline?
6.If I was able to build a magical 1000-stage pipeline, where each stage took an equal amount of time, what speedup would I get?

Consider two less-than-desirable options. in the first you are driving 30 mph and crash head-on into an identical car also going 30 mph. in the second option you are driving 30 mph and crash head-on into a stationary brick wall. in neither case does your car bounce off the thing it hits, and the collision time is the same in both cases. which of these two situations would result in the greatest impact force?
