US Patent 9323794 Method and system for high performance pattern indexing

Disclosed herein is a method and system for accelerating the generation of pattern indexes. In exemplary embodiments, regular expression pattern matching can be performed at high speeds on data to determine whether a pattern is present in the data. Pattern indexes can then be built based on the results of such regular expression pattern matching. Reconfigurable logic such a field programmable gate arrays (FPGAs) can be used to hardware accelerate these operations.
