Question

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

• A. T1 plus T2 is the time taken for one instruction fetch cycle
• B. T1 $\ge$ T2
• C. T1 < T2
• D. T1 $\le$ T2

Answer 1

The correct option is B T1 $\ge$ T2

In pipelined CPU, there will be buffer delay and stage delay. So for 1 instruction nonpipelined CPU takes less time compared to pipelined CPU.
