Intermediate Topic 32 of 51 Computer Architecture & Logic
Pipeline Hazards
Data, control and structural conflicts that stall pipelines.
How it works
Structural hazards: resource conflicts. Data hazards: an instruction needs a result not yet written (solved by forwarding or stalls). Control hazards: branches change flow.
Where it is used
Understanding why code stalls.
Common pitfall
Deeper pipelines make mispredictions costlier.
