Abstract
Prediction circuitry generates a prediction associated with a prediction input address, for controlling a speculative action. Combiner circuitry determines a combined prediction by applying a prediction combination function to a given address and sets of prediction information generated by a plurality of predictors corresponding to the given address. A cache structure comprises combiner cache entries. A given combiner cache entry associated with an address indication indicates items of combined prediction information for an address corresponding to the address indication and different combinations of possible values for the respective sets of prediction information. Lookup circuitry looks up the cache structure based on the prediction input address to identify a selected combiner cache entry, and generates the prediction based on combined prediction information selected from the selected combiner cache entry based on the respective sets of prediction information corresponding to the prediction input address.
