Claims

[Scope of utility model registration request]

a central arithmetic processing unit that executes predetermined instructions and has arithmetic processing capability; a micro fixed storage unit that stores a processing sequence for the arithmetic processing unit;
For the micro fixed storage unit, there is a map fixed storage unit that stores the start address of the microprogram to be processed, and a map fixed storage unit that stores the start address of the microprogram to be processed, and a map fixed storage unit that stores the calculation result of the central processing unit or the output of the map fixed storage unit. In a computer equipped with a selector for selecting a start address, a counter capable of setting a certain predetermined time, and a driver and a display device for displaying an abnormality when a microprogram processing sequence takes more than the above set time are added. A computer characterized in that, when an abnormal processing sequence of a microprogram occurs, it can be displayed externally.
