| Zusammenfassung: | PROBLEM TO BE SOLVED: To provide an error detection method related to an multi-bit error, preventing latency of an error of a storage device by a fixed error or a soft error of the storage device, in a high-reliability controller realized by a multiplex configuration of processors. SOLUTION: This high-reliability controller having a plurality of processing systems comprising the processors 2 and the storage devices 3, and performing the same processing by the plurality of systems is provided with a comparison device 1 having a self-check function. In the high-reliability controller, by accessing the storage device in an idle time inside a control cycle and making it comparison-operate, error detection is performed.
