To improve the probability of error correction, thereby generating correct read data. Data is read from the same sector by a number of times and a majority decision is done in the same address, thereby the most frequently read value is regarded as the true data value in the address. For example, for an address 00, “00” is handled as a true data value.

An error rate of a bit synchronous circuit is decreased to a large extent by preventing following excessively the jitters included in input data. A phase detect circuit of a bit synchronous circuit includes a majority decision circuit. The majority decision circuit counts UP0 and DN0 signals as a phase comparison result of comparing phases by a UP0 counter and a DN0 counter for a period of time, and its count number is judged by a magnitude relation determination circuit. The magnitude relation determination circuit outputs an UP signal if the UP0 signal is majority, a DN signal if the DN0 signal is majority, and a FIX signal if the UP0 signal is equal to the DN0 signal. Accordingly, since it is possible to prevent following the jitters included in input data, etc., an error rate for bit synchronization can be reduced to a large extent.

A redundant information processing system with sufficient reliability is provided at a moderate cost without any part that could be a single fault point in the system. In the redundant information processing system in which an actuator 5 is controlled based on a signal from a sensor 4, each of processing devices 1A to 1C collects command signals from other processing devices and determines which command signal to be valid according to a logical decision, for example, a majority decision.
