PURPOSE:To simplify the constitution of the titled system by forming an output part for detecting an instruction for a prescribed shift and outputting a specific bit independently of a shift processing part, connecting the output part to an input storage part and forming a specific bit storing part. CONSTITUTION:A shift-out bit control circuit 23 is formed independently of a shifter and both the circuit 23 and shifter 22 are respectively connected to an input data register 1, the output of the circuit 23 is to be set up in a storing FF 24, both the circuit 23 and shifter 22 are connected to a shift control information register 25, and the output of the shifter 22 is stored in a result register 6. Since a specific shift-out bit is set up in the FF 24, it is unnecessary for the shifter 22 to consider fixed bit shift control. |
