PURPOSE:To enable initializing effectively with a simple method when the control information is set to the control register, by providing the initializing set which initializes the arithmetic output data register and the arithmetic input data register. CONSTITUTION:The system is provided with the arithmetic result register 1 to which the operation output data is set, a plurality of multiplicand registers 2, multiplication register 3 and control register 4 to which the control data is set, and the write signal from the signal line l and the control information are added to the register 4. Further, the multiplexers 5-7 are connected to the registers 1-3, and the write signal and the data are input to the multiplexers 5-7. Further, all 0 data is input to the multiplexers 5-7, the control information is fed to the register 4, the signal line l is taken as 1, the control information is set to the register 4, and 0 data is input to the multiplexers 5-7 with 1 on the signal line l at the same time, to effectively initialize the registers 1-3. |
