摘要:
An information processing system for branch target prediction is disclosed. The information processing system includes a memory for storing entries, wherein each entry includes a plurality of target addresses representing a history of target addresses for a multi-target branch and logic for reading the memory and identifying a repeated pattern in a plurality of target addresses for a multi-target branch. The information processing system further includes logic for predicting a next target address for the multi-target branch based on the repeated pattern that was identified.
