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.
