3. Assume a non-pipelined processor takes 100ns to process an instruction. The sameinstruction can be executed in a 5-stage pipelined processor, where each stage takes 20 ns. (i) What is the minimum number of instructions for which the speedup achieved by the pipelined processor (compared to the non-pipelined processor) is at least 4? (ii) The instruction takes the same time (100 ns) to execute whether on the pipelined processor or on the non-pipelined processor. So why do we say pipelining speeds up execution?

3. Answer the question
![3. Assume a non-pipelined processor takes 100ns to process an instruction. The sameinstruction
can be executed in a 5-stage pipelined processor, where each stage takes 20 ns.
(i) What is the minimum number of instructions for which the speedup achieved by the pipelined
processor (compared to the non-pipelined processor) is at least 4?
