摘要
Provided is a finite automaton circuit generating device capable of reducing the number of states or the amount of calculation.A finite automaton generating device (1) is provided with an input device (11) for receiving the input of a regular expression and the number of action characters, a 1-character FA generating section (21) for generating a 1-character FA on the basis of the regular expression, a multi-character conversion preprocessing section (22) for substituting state transition for multi-character conversion for repeated regular expressions included in the 1-character FA on the basis of the number of action characters, a multi-character FA conversion section (23) for generating a multi-character FA from the 1-character FA by using the state transition for the multi-character conversion and the number of action characters, and a multi-character conversion post-processing section (24) for substituting repeated regular expressions in units of the number of action characters for repeated regular expressions not less than the number of action characters in the multi-character FA.
