Firstly the branching transitions are augmented with the check instruction and the backward transitions are eliminated; then the parallel detection mechanism is used, the original thread is replaced by the two parallel threads which are in order to accelerate the speed of matching: the pre statistical thread and the state machine matching thread. The experiments show the algorithm has a faster speed and stability, and is suitable for multi-core computing environments. %U http://cea.ceaj.org/EN/abstract/article_29737.shtml
