PURPOSE:To reload a program without stopping a data processor or a central processing unit by executing the program, which is stored to a main storage, while the program is reloaded. CONSTITUTION:When the reloading information of a microprogram stored in a control storing part 53 are received from a diagnosis device 40, a central processing unit 50 stops the microprogram which is presently read from the control storing part 53 and executed. Then, the microprogram, which is stored in a main storage 10, to be executed during the reloading of the microprogram to the control storing part 53 is read and executed. At such a time, the diagnosis device 40 executes the reloading of the microprogram to the control storing part 53. Thus, constitution is simplified and the contents of the program can be reloaded without stopping the data processor or central processing unit.
