How pipelining is classified ?OR Write short notes on instruction pipeline.

Arithmetic Pipelining:
- What it is: Imagine a computer performing math calculations. Arithmetic pipelining breaks down the math operations into stages, like a production line, where each stage handles a specific part of the calculation.
- Examples: Some computers, like Star-100 or TI-ASC, use this method with different numbers of stages to process arithmetic tasks efficiently.

Processor Pipelining:
- What it is: Picture a relay race where different runners handle specific tasks in a sequence. In processor pipelining, a series of processors work on the same data stream. Each processor specializes in a particular job, and the results are passed from one to the next.
- Example: The data moves through the processors, with each one refining the results, but it’s not widely adopted yet.

Instruction Pipelining:
- Also known as: Sometimes called “instruction look ahead” because it’s like the computer is looking ahead at the next instructions.
- What it is: Think of assembling a product on an assembly line. Instruction pipelining involves breaking down the execution of instructions (commands) in a computer into stages. While one instruction is being executed, the next one is already being fetched, decoded, and prepared for execution.
- Common usage: Most high-performance computers nowadays use instruction pipelines to enhance the speed of instruction execution.
