ABSTRACT:
A minimum distance storage device for storing distances obtained in pattern recognition as arranged in the ascending order easily generates addresses with no need for multiloop control and at the same time of detects a minimal distance of the same category. A read-out distance read from a result memory and temporarily held in a first register, and an input distance input from a distance calculating portion and temporarily held in a second register, are compared with each other by a second selector. The read-out distance, if smaller than the input distance, is written in the same place where it was stored in the result memory. If the read-out distance is larger than the input distance, the latter is written in the place where the read-out distance was stored and, then, the larger read-out distance and other read-out distances are written in places moved to the right each by one in sequence in the result memory.
