Abstract
An instruction supplier for a microprocessor prevents a functional error operation of the microprocessor. In the instruction supplier, an instruction register temporarily stores an inputted instruction therein, and an instruction memory stores at least one instruction therein. At least one comparator is provided for detecting whether or not at least one instruction stored in the instruction memory agrees with the instruction stored in the instruction register, respectively, by comparing them, and for outputting a comparison result signal for indicating the comparison result. Furthermore, an instruction generator generates at least one specific instruction in accordance with the comparison signal, and then, an instruction selector selects either one of the instruction stored in the instruction register and the specific instruction generated by the instruction generator to be executed, and outputs the selected instruction.
