Design a fast CAM-based information detection system on FPGA and 0.18#x00B5;m ASIC technology

摘要

A novel information detection method has been proposed for a fast and efficient search engine. This method is implemented on hardware system using FPGA in advance for functional verification and then on ASIC using 0.18µm CMOS technology. We take advantages of Content Addressable Memory (CAM) which has an ability of parallel multi-match mode for designing the system. The system operates based on CAM blocks for pattern matching in parallel manner to return multiple addresses of multi-match results. Based on the parallel multi-match operations, the system can be applied to pattern matching or searching applications with various constraint search patterns without using any search principles. This increases the matching performance of the search systems.
