  • Finite state automaton with multiple state types
    Patent number: 4241402
    Abstract: The subject of this disclosure is a Finite State Automaton (FSA) used as part of a term detector employed in a digital pattern search system (searcher). In particular the invention includes various advances in the art of FSA design which make the FSA practical for pattern recognition.Specifically, these advances minimize the amount of memory which is required in each FSA in performing pattern recognition, and allow a speed capability such that the searching can be performed at the rate at which a mass storage medium can supply data. The large amount of memory required and the low speed of processing in the prior state of the art made the use of an FSA impractical for most real applications.
