PURPOSE:To improve the system developing efficiency by changing temporarily the contents of a microprogram without transforming and oil system itself against the change of contents of the microprogram when a new system is developed and attaining an inspection through execution of a normal state. CONSTITUTION:A system developer applies the change of a microprogram level to a microprogram in a CS10 and executes and inspect it during execution of a normal state. In such a case, the control conditions are first set to a microconverter 20 via a control part 22. Then a computer system is actuated in a normal state. A control circuit 12 reads sequentially the microinstructions out of the CS10 and sends them to a data bus 18 via a selector 16 and also to the converter 20. Then it is checked whether the microinstruction is equal to a subject of conversion or not. If it is decided that the microinstruction is equal to a subject of conversion, the converter 20 delivers a substitute microinstruction obtained previously and sends it onto the bus 18. |
