PROBLEM TO BE SOLVED: To perform minute operation control without affecting the other function. SOLUTION: Register groups 3 and 5 are connected to input ports of an ALU 1 through selectors 4 and 6. Data inputted to the ALU 1 are kept in a register that the selectors 4 and 6 select in accordance with a sequencer 2. When registers 1 (3a and 5a) are selected in a prescribed application and it is switched to the next application, the register that the selectors 4 and 6 select is switched by an instruction of the sequencer 2 after the previous application is terminated. Since data of the previous application are left in the registers 1 (3a and 5a), data are not discharged after termination of the application and the next application can immediately be started.
