Abstract
PURPOSE: To ensure the self-diagnosis for the information processor containing both forward and backward conversion means by comparing the input of one side with the output of the other side.
CONSTITUTION: At the forward conversion time, input (a) is stored in register 6-2 via register 2 and then OR circuit 6-1. Output (c) underwent the forward conversion undergoes the backward conversion through backward conversion circuit 1-2 via register 3 and 4 to be supplied to register 5. Output (h) of register 5 is supplied to exclusive logic sum circuit 6-4 via OR gate 6-3 to secure the exclusive logic sum with output (j) of register 6-2. In case no coincidence is obtained, the fact that some fault has occurred at either one of register groups 2W5 including information converting part 1 is reported to the central process unit. The same operation is given also at the backward conversion time with the difference only in the direction.
