The pattern sequence is an expression that is a statement in a language designed specifically to represent prescribed targets in the most concise and flexible way to direct the automation of text processing of general text files, specific textual forms, or of random input strings. Regular Expressions (RE) are getting popular still under developed stage of their inherent complexity that limits the total number of RE that can be known by using a single chip. This limit on the number of RE doesn't pair with the scalability of present RE detection systems. Existing schemes is limited in the old detection paradigm based on per-character-state working and also state transition detection.
