WebbUNIT-III Page 5 Pipeline Hazards A pipeline hazard occurs when the pipeline, or some portion of the pipeline, must stall because conditions do not permit continued execution. Such a pipeline stall is also referred to as a pipeline bubble. There are three types of hazards: resource, data, and control. Webb11 dec. 2024 · 23. Pipeline HazardsCSCE430/830 Pipelining Summary • Speed Up <= Pipeline Depth; if ideal CPI is 1, then: • Hazards limit performance on computers: – Structural: need more HW resources – Data (RAW,WAR,WAW) – Control Speedup = Pipeline Depth 1 + Pipeline stall CPI X Clock Cycle Unpipelined Clock Cycle Pipelined. 24.
http://users.ece.northwestern.edu/~kcoloma/ece361/lectures/Lec12-pipeline.pdf Webbpipelining: In computers, a pipeline is the continuous and somewhat overlapped movement of instruction to the processor or in the arithmetic steps taken by the processor to perform an instruction. Pipelining is the use of a pipeline. Without a pipeline, a computer processor gets the first instruction from memory, performs the operation it ...
WebbStalling the pipeline •Freeze all pipeline stages before the stage where the hazard occurred. • Disable the PC update • Disable the pipeline registers •This essentially equivalent to always inserting a nop when a hazard exists • Insert nop control bits at stalled stage (decode in our example) • How is this solution still potentially “better” than relying
