| Abstract | (in Japanese) | (See Japanese page) |
| (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 requires 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． |
