A branch prediction method executed in a branch prediction circuit executes the branch instruction, the branch prediction method includes: a branch information storing process for storing the information in the first storage unit or the second storage unit; a process for determining on the basis of a branch condition set by the branch instruction and a realized branch whether the branch prediction is realized; a rewriting process for performing a rewrite of the information in one of the first storage unit and the second storage unit in accordance with the determination and the degree of likelihood that a branch indicated by the branch prediction occurs; and a process for performing branch prediction in response to the branch information when the branch instruction is executed in the processor.
