Abstract
A system for speculative branch predictions. An embodiment of the system includes branch prediction logic, fetch logic, and branch identification logic. The branch prediction logic is configured to predict a branch path for a branch in an instruction stream. The fetch logic is coupled to the branch prediction logic. The fetch logic is configured to speculatively fetch an instruction corresponding to the predicted branch path. The branch identification logic is coupled to the branch prediction logic and the fetch logic. The branch identification logic is configured to mark the speculatively fetched instruction with a branch identifier using a universal branch identification format. The universal branch identification format includes a bit value at a bit position corresponding to the predicted branch path.
