  • State machine based filtering of non-dominant branches to use a modified gshare scheme
    Publication number: 20050257036
    Abstract: Disclosed is a method and apparatus providing the ability to create a multi-level prediction algorithm where branch predictions beyond the first level of prediction are maintained at a secondary level because the prior level was unsuccessfully able to highly predict accurate the direction of the stated branch. A secondary level is smaller in size than the upper level through selected filtering thereby enabling high prediction accuracy of branches while minimizing the amount of hardware to perform stated predictions.
