Abstract
A method of branch prediction in a processor includes: obtaining, by the processor, a branch instruction for which a direction of a branch is to be predicted; generating, by the processor, an index based on an instruction address, a global path vector (GPV), and a counter; selecting, by the processor, an entry from a data structure using the index; and predicting, by the processor, the direction of the branch using information included in the selected entry. The method may include modifying a tag in the selected entry based at least in part on another GPV.
