Claims

[Scope of utility model registration request]

a central arithmetic processing unit that executes predetermined instructions and has arithmetic processing capacity; 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 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 starting address, a counter that can set a predetermined number of microsteps, and a driver and a driver for displaying an abnormality when the processing sequence of the microprogram takes more than the set number of microsteps. A computer characterized in that by adding a display device, when an abnormal processing sequence of a microprogram occurs, it can be displayed externally.
