What is pipelining?
A technique where multiple instructions are overlapped in execution.
🌐 Termos em outros idiomas:
Pipelining is like an assembly line for CPU instructions. Instead of waiting for one instruction to finish all its stages before starting the next, a pipelined CPU starts fetching the second instruction as soon as the first one moves to the Decode stage.

Pipelining is like doing laundry with a separate washer and dryer. You start the second load in the washer while the first load is still in the dryer. This way, both are working at once!

Pipeline hazards (Data, Control, Structural) can cause stalls or 'bubbles'. Branch prediction is essential to keep the pipeline full. A pipeline 'flush' occurs when a branch guess is wrong.
