A Scalable Hybrid Regular Expression Pattern Matcher

In this paper, the authors present a reconfigurable hardware architecture for searching for regular expression patterns in streaming data. This new architecture is created by combining two popular pattern matching techniques: a pipelined character grid architecture (Baker, 2004), and a regular expression NFA architecture (Cho, 2006). The resulting hybrid architecture can scale the number of input characters while still maintaining the ability to scan for regular expression patterns
