Abstract

PURPOSE:To diagnose an address by a diagnostic data from the keyboard, and elevate the reliability as an information processing equipment, by adding a simple fluction to the information processing equipment. CONSTITUTION:Start of processing is instructed to the control part C1 of the information processing equipment A from the operation part K, an address to be processed is sent to the external memory device M1 through the gate G1 from the control part C1, and address information of the address part is input to the comparator circuit COM as an output information from the device M1. Also, the address from the control part C1 is input to the latch R1 through the gates G3, G2, the output of the latch R1 is provided to the circuit COM simultaneously with the address part from the device M1, and the result of its comparison is set to the flip- flop F1. A diagnostic switch SW is placed on the operation part K of this information processing equipment, and when the address is compared by the circuit COM and it is decided whether the control system is normal or not, it is made possible to easily discriminate whether it is normal or not, by a different address from the switch SW, and to elevate the reliability of the information processing equipment.
