摘要：
A system for validating branch predictions for clusters of branch instructions includes an address validation module and a condition validation module. The address validation module determines target addresses for the branches in the cluster. One of the determined target addresses is selected, using predicted branch directions. The selected target address is compared with a predicted target address, and resolved branch directions are compared with predicted branch directions. A misprediction is indicated if either comparison fails.
