Abstract
A branch prediction scheme predicts whether a computer instruction will cause a branch to a non-sequential instruction. A prediction counter is selected by performing an exclusive or (XOR) operation between bits from an instruction address and a hybrid history. The hybrid history, in turn, is derived by concatenating bits from a global history register with bits from a local branch history table. The bits from the local branch history table are accessed by using bits from the instruction address.
