Accelerating Search and Recognition Workloads with SSE 4.2 String and Text Processing Instructions

Today's information is increasing rapidly, doubling every three years. Consequently, the search and recognition stages in computer applications will consume a growing portion of the total CPU time. The SSE 4.2 instruction set, first implemented in Intel's Core i7, provides String and Text New Instructions (STTNI) that utilize SIMD operations for processing character data. Though originally conceived for accelerating string, text, and XML processing, the powerful new capabilities of these instructions are useful outside of these domains, and it is worth revisiting the search and recognition stages of numerous applications to utilize STTNI to improve performance.
