Multi-pattern matching algorithm has been widely used in text searching, intrusion detection, and some other areas. We focus on two matching algorithms, AC and regular expression. By comparing their DFA automata building process, we integrate the two processes to a new novel AC algorithm. The new AC maintains the advantages of the traditional AC when matching fails, the pointer of the target pattern does not turn back, and the AC automata pointer just moves back by a few steps. Meanwhile, we also discuss the AC parallelization based on GPU and CUDA, and compare the running performance when using GPU global memory or the texture one.
