Original Abstract Submitted
A method of branch prediction includes determining that a processor is to execute at least a portion of a first set of instructions. An address associated with a sequentially first instruction of the first set of instruction is determined, and a branch prediction index is determined based on the address and a branch history. A table is queried based on the branch prediction index to determine a predicted exit point of the first set of instructions. The processor fetches a subset of the first set of instructions based on the predicted exit point.
