Key idea: Pipelining improves throughput (instructions/time), not the latency of a single instruction.

1) Introduction (Non‑pipeline vs Pipeline)

Non‑pipelining

CPU finishes one instruction completely and then starts the next.

Pipelining

CPU starts the next instruction before the previous one is fully finished.

So multiple instructions are in different stages at the same time, improving overall performance.

2) Definition (Exam)

Pipeline is a technique in which the execution of an instruction is divided into multiple stages, and different instructions are processed simultaneously in different stages.

Important points

• ✅ Pipeline does not reduce the time of one instruction.
