Abstract:
Embodiments of apparatuses, methods, and systems for misprediction-triggered local history-based branch prediction are described. In one embodiments, an apparatus includes a current pattern table and a local pattern table. The current pattern table has a plurality of entries, each entry in which to store a plurality of pattern lengths of a current pattern of one of a plurality of branch instructions. The local pattern table is to provide a first branch prediction based on the current pattern.
