1. a data processor, comprises:

  • There is the instruction buffer storer of multiple storer;

    Branch prediction data storage unit, described branch prediction data storage unit occurs or nonevent predicted data in order to the conditional branching storing branch instruction, and when described conditional branching occurs, store the predicted data of that storer of the data storing described branch instruction in the middle of described multiple storer;

    AndRead active control unit, this reads active control unit in order to when the instruction that will be performed is branch instruction, occur or nonevent predicted data by using the described conditional branching obtained via the index corresponding with described branch instruction from described branch prediction data storage unit, and the predicted data of that storer of the data of the described branch instruction of described storage, activation control signal will be read and output to described multiple storerWherein, read activation control signal by output to be activated to cause that storer being predicted to be the data storing described branch instruction in multiple storer.
