Explanation : Pipelining does not increase the execution time
of a single instruction. It increases the overall
performance by executing instructions in multiple
pipeline stages.
For N=1
Pipelined CPU :
Total time (T1) = (K + (N – 1)) * T = KT
Non-Pipelined CPU :
Total time (T2) = KNT = KT
Considering buffer delays in pipelined CPU,
T1 > = T2
