ABSTRACT:
Briefly, a method and apparatus of branch prediction is provided. The branch prediction may be done by performing a XOR operation between MSB of set bits of a path register with LSB of set bits of an instruction pointer address register to provide a global index, and by performing a XOR operation of LSB tag bits of the path register with MSB tag bits of the instruction pointer address register and providing a tag index. There may be multiplexing between a global prediction to a local prediction.
