Pipeline and Vector Processing Q.2

0. Comparing the time T1 taken for a single instruction on a pipelined CPU with time T2 taken on a non-pipelined but identical CPU, we can say that

  • Option : B
  • 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
