Product Overview

Perl Compatible Regular Expressions

Description: Perl Compatible Regular Expressions (PCRE) is a C library that implements regular expression pattern matching with the same syntax and semantics as Perl 5. PCRE is very fast and highly portable.

Hyperscan

Description: Hyperscan is a high-performance regular expression matching library. It is designed to accelerate pattern matching workloads on streaming input data by taking advantage of modern processor architectures. Hyperscan works by compiling regex patterns into specialized programs that execute regex searches faster.
