Abstract:
1. A matching device that selects, in character recognition, using a characteristic amount of a first character as a recognition object and characteristic amounts of a plurality of second characters registered in a dictionary in advance, P second characters similar to the first character among the second characters as recognition candidates, where P is an integer equal to or larger than two, the matching device comprising: a first storing unit that stores a plurality of first characteristic amount data indicating the characteristic amount of the first character and a plurality of dictionary data including second characteristic amount data indicating the characteristic amounts of the second characters and character codes of the second characters; a semiconductor device including a circuit unit in which a circuit is rewritably configured and a second circuit is configured after a first circuit is configured and a control unit that controls rewriting of the circuit configured in the circuit unit; and a second storing unit that stores first circuit configuration data for configuring the first circuit in the circuit unit and second circuit configuration data for configuring the second circuit in the circuit unit, wherein the first circuit includes the second circuit includes the control unit reads out the first circuit configuration data stored in the second storing unit and configures the first circuit in the circuit unit and, then, when the P first distances and the first character codes are respectively input to the k third memories of the first circuit, reads out the second circuit configuration data stored in the second storing unit and rewrites the circuit configured in the circuit unit to the second circuit while keeping the P first distances and the first character codes in the k third memories, respectively.
