Abstract(in English) | Regular expression pattern matching is a problem to find substrings in a given text, which match with a pattern represented by regular expression. We have proposed regular expression pattern matching hardware that can realize iteration of a single character using quantifiers. However, some applications require patterns that include iteration of a subclass of regular expression, such as union of strings and negation of a character, using quantifiers. In this paper, we propose a hardware algorithm that can realize iteration of such a subclass of regular expression using quantifiers. FPGA implementation results show that the proposed algorithm significantly reduces the number of LUTs needed to realize those patterns. |
