Pipelining is an implementation technique where multiple instructions are overlapped in execution.
The computer pipeline is divided in stages. Each stage completes a part of an instruction in parallel.
All the common steps involved in instruction processing by the CPU can be pipelined:
- Instruction Fetching -[IF]
- Instruction Decoding -[ID]
- Operand Loading -[OL]
- Execution -[EX]
- Operand Storing -[OS]
A pipelined system is often compared to an assembly line on which many products are in various stages
of manufacture at the same time. In a non-pipelined CPU, instructions are exexuted in strict sequence.
Pipelining permits the situation shown in figure where each major step of instruction processing
is assigned to,handled independently by, a separate subunit of the CPU pipeline.
