<ul data-eligibleForWebStory="true">Modern processors achieve high performance through pipelining, executing multiple instructions in parallel.Pipelining splits CPU tasks into specialized stages, analogous to an assembly line, improving efficiency.In a pipelined system, each stage processes a specific task, allowing for simultaneous instruction execution.Data hazards can cause stalls in CPU pipelines when dependencies between instructions arise.Control hazards, like branching decisions, can slow down pipelines as CPUs await evaluation results.Structural hazards occur when multiple instructions require the same CPU resource simultaneously.Pipeline stalls, or bubbles, can be managed using various techniques like hazard detection units and out-of-order execution.Understanding these bottlenecks is crucial in optimizing pipeline efficiency and overall CPU performance.The article discusses how pipelining works, CPU pipeline stages, and strategies to overcome pipeline limitations.Future articles will delve deeper into solutions for data, control, and structural hazards in CPU pipelining.
