Instruction Pipeline A series of stages through which instructions pass in a processor pipeline, each stage carrying out a specific operation.
Pipeline Flush The process of discarding all instructions in a pipeline due to a misprediction or hazard, and restarting the pipeline.
Pipeline Hazard A condition in processor pipelining where the next instruction cannot execute in the next stage due to a dependency or conflict.
Processor Pipelining A technique in computer architecture that allows multiple instruction stages to be overlapped in order to improve efficiency and performance.
Structural Hazard A condition in processor pipelining where the hardware is unable to support overlapping of certain stages.
