WebOct 3, 2024 · When a stall is present in the pipeline, then CPI (Cycle per Instruction) ≠ 1. There are three types of hazards possible in the pipeline, namely: Structural Hazards. … WebDec 22, 2024 · Pipelining Gate Questions with Solutions. Some pipelining gate questions with solution are explained here. Q1. There is an instruction pipeline with four stages. The stage delays for each stage is 5 nsec, 6 nsec, 11 nsec, and 8 nsec respectively. Consider the delay of an inter-stage. register in the pipeline is 1 nsec.
