What is pipelining?


  • In networking a task begun before the previous task has ended is known as pipelining.

  • Pipelining in a processor allows storing and executing many instructions in an orderly way. Here multiple instructions are overlapped during execution.

  • Pipeline is divided into stages connected with one another. Like a pipe instructions enter from one end and exit from another end. Each “stage” of pipeline consists of an input register followed by a combinational circuit. The register holds data and combinational circuit performs operations on it. The output of combinational circuit is applied to the input register of the next segment.

  • Pipeline system like the modern day assembly line setup in factories increases the overall instruction throughput.
