Design of a parallel CAM-based multi-match search system using 0.18-µm CMOS process

Abstract

A novel data matching method has been proposed for a very fast and efficient search engine. This method is implemented on 0.18-μm CMOS process. We take advantage of Content Addressable Memory (CAM) which has an ability of parallel multi-match mode for designing the system. The system operates based on the CAMs for pattern matching in parallel manner to return multiple addresses of multi-match results. This principle increases search performance of the search system. Based on the parallel multi-match operations, the system can be applied to pattern matching or searching applications with various constraint query patterns without using any search principles.
