ABSTRACT:
A data match detecting apparatus which sequentially receives input data comprising plural fields, comprises parameter storage which contains a parameter group comprising plural parameters which are checked to detect a match between the plural fields and the plural parameters; parameter selector for selecting a parameter corresponding to a field input as the input data from the parameter storage and outputting the selected parameter; data comparator for checking match between the parameter output from the parameter selector and the input data; a comparison result storing circuit initialing its storage content to match before a first field of the input data for which match detection should be performed is input, storing a comparison result of a comparison result decider when there is an input field, and outputting its storage content when all the fields of the input data for which match detection should be performed have been input; and the comparison result decider storing match in the comparison result storage when the storage content of the comparison result storage and the comparison result of the data comparator are match.
