  • Hybrid branch prediction using a global selection counter and a prediction method comparison table
    Patent number: 6938151
    Abstract: A microprocessor and method for branch prediction selection provides the capability to select among multiple direction based history arrays for a single branch. A global selection counter when used in conjunction with a Prediction Method Comparison Table (PMCT) allows for branch direction accuracy to be improved on cold starts and context switches while maintaining high accuracy on long running code while minimizing silicon area and reducing power requirements.
    Type: Grant
    Filed: June 4, 2002
    Date of Patent: August 30, 2005
    Assignee: International Business Machines Corporation
    Inventors: James J. Bonanno, Nidhi Nijhawan, Brian R. Prasky
