Q1) (i) Briefly discuss the terms: (a) pipelining and (b) instruction latency. Consider a non-pipelined machine with 6 execution stages of length 60 ns each. (ii) Find the instruction latency on this machine. (iii) How much time does it take to execute 500 instructions?

Q2) Suppose we introduce pipelining on the machine mentioned in Q1. (i) How much time does it take to execute 500 instructions? Calculate the actual time. (ii) What is the instruction latency on the pipelined machine? (iii) Is there any performance improvement (due to pipelining)? Please explain.
