This paper proposes a high-speed string matching circuit for searching a pattern in a given text. In the circuit, a pattern is specified by a class of restricted regular expressions. The architecture of the proposed circuit is a one-dimensional systolic architecture consisting of simple processing units. It can be effectively used for network intrusion detection systems (NIDSs).
