出来ることを特徴とする計算機。 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 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 results of the central processing unit or the map fixed storage unit that stores the start address of the microprogram to be processed. In a computer equipped with a selector for selecting a start address, a counter that can set the number of microsteps to be executed when executing a certain predetermined instruction, a counter that can measure the number of microsteps to be executed, and a microprogram processing sequence set as above. A computer characterized in that, by adding a comparator and a display device for comparing the number of microsteps and the number of measured microsteps, it is possible to externally display when an abnormal processing sequence of the microprogram occurs.
