Abstract
PURPOSE:To increase the processing speed of a branch instruction and to improve a processing performance by using the output of a branch instruction counting circuit for control conditions concerning a branch instruction and switching the input of two instruction registers of an instruction decoding circuit. CONSTITUTION:An instruction is read from a main storage device 1, decoded by an instruction decoding circuit 5 and executed by an instruction executing circuit 7. By the instruction execution, the number of the success and failure of the branch in the branch instruction is given to a branch instruction counting circuit 9. The counting circuit 9 uses the counting result for the control conditions concerning the branch instruction. For example, a branch instruction switching circuit 8 is controlled, and the instruction decoding circuit 5 and two instruction registers 3 and 4 are switched based on the branch success or the failure priority. When the switching circuit 8 receives a special instruction related to the branch success, the register 4 is selected and the input of the instruction decoding circuit 5 is switched to the register 4 side.
