A computerized dual-system interlocking apparatus offers a fast processing speed, an improved utilization and an easy-to-test characteristic, with a start/stop function provided in data matching between two CPUs. The apparatus comprises a data matching circuit (16) for determining data match between sets of data resulting from identical processes performed by a first CPU(7) and a second CPU(13) on identical input information, and wait circuits (19, 21) for making the first CPU(7) and second CPU(13) wait in standby for the processes during data matching operation, and for releasing the first CPU(7) and second CPU(13) free from the standby state when the data matching circuit (16) determines that the sets of data match, and a reset circuit (5) for issuing reset signals to the first CPU(7) and second CPU(13) when the sets of data fail to match. |
