Abstract
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.

Claim 1
Independent Claim
242 words
A data processor comprising: data detecting portion having a plurality of parallel input ports and a plurality of data transmission paths subsequent to the input ports for detecting data existing in a finite section on each of the data transmission paths with respect to data transmitted through each of the data transmission paths and further including a plurality of latches, each said latch having a plurality of stages; coexistence detecting portion for detecting data simultaneously coexisting in said data detecting section of at least three set of said data transmission paths based upon the detection of the data detecting portion; comparing and determining portion for extracting identifiers for identifiers data from each of said data transmission paths, each said identifier including at least a portion of the data detected by said data detecting portion, and for comparing and determining the relationship between the identifiers; data processing portion for processing the detected data by adding a signal indicating the determined relationship to the detected data and for changing at least a portion of the detected data; and output ports, subsequent to the data transmission paths, for outputting a plurality of data from the plurality of latches, wherein the plurality of data is detected and compared during data transmission with respect to inputs of at least three parallel sets of said data transmission paths, the plurality of data being processed based on the result of the comparison and detection without disturbing said data transmission.
Claim 2
Dependent Claim
