Abstract
PURPOSE: To detect the wrong address in the information processing device by forming the circuit which judges if the interrupt inhibition bit in the micro-instruction and the address of the micro-instruction have been subject to adressing.
CONSTITUTION: The address 5 is stored in the register 7 by receiving the micro- instruction address 5 and its receiving signal 6 from the information processing device 1, its contents are stored in the register 8 with the timing T3, these contents are subtracted by the subtraction circuit 9, and in case its result is not "1", "1" is set to INCFF 10 with the timing T2. Subsequently, AND is taken by the AND circuit 12 concerning the output of FF 10 and the output of the interrupt inhibition bit FF 3, and the signal of the mode changeover instruction signal 11, and it is set to the error FF 13 with the timing T3. And in case FF 13 has been set to ON, the error detection signal 14 becomes ON, and this signal is transmitted to the information processing device 1.
