Hybrid branch predictor using component predictors each having confidence and override signals
Abstract:
Various embodiments are described relating to processors, branch predictors, branch prediction systems, and computing systems. In an example embodiment, a processor includes a plurality of branch predictors. Each branch predictor is adapted to provide a prediction and an override signal. In the example embodiment, the processor futher includs a branch prediction control circuit. The branch prediction circuit is adapted to generate a branch prediction based on the prediction and the override signal from each predictor.
