Abstract
A pipelined processor includes a main memory, an instruction cache, a BTB, and a BTB registration discriminator for decoding instructions line fetched from the main memory at the time of mishit of the instruction cache and for registering branch information in the BTB when the instruction is a branch instruction. Since the branch information is already stored in the BTB even at the first execution time of the branch instruction, a branch prediction hit ratio is improved.
