Study Notes
Pipelining Analogy
- Pipelining can be understood by visualizing a laundry process, where each stage is executed in parallel.
- This overlapping execution significantly enhances performance.
Pipelining Overview
- Pipelining involves dividing a task into multiple stages that can be executed concurrently.
- This approach allows for the processing of multiple instructions at the same time, improving overall performance.
Speedup with Pipelining
- Consider a situation with four loads and a pipeline with three stages.
- The speedup is measured as the ratio of execution time without pipelining to execution time with pipelining.
- In this example, the speedup is approximately 2.3.
Ideal Speedup
- In an ideal scenario with no pipeline overhead, the maximum speedup is achieved when the number of stages equals the number of instructions.
- This ideal speedup is theoretically equal to the number of pipeline stages.
