Abstract
So-called template matching processing is function-distributed into a pre-detecting portion and a template matching portion, processing in the respective portions being achieved by a hardware circuit. In the pre-detecting portion, the relationship between data which simultaneously exist in the determined comparing sections on data transmission paths, and matching processing is performed in advance with respect to data to be matched. The template matching portion includes an addressing type general-purpose memory and performs main processing of template matching based on the result of the comparison and determination in the pre-detecting portion.
