Abstract:
A data match detecting apparatus which sequentially receives input data comprising plural fields, comprising:parameter storage means which contains a parameter group comprising plural parameters which are checked to detect match between the plural fields and the plural parameters;parameter selecting means for selecting a parameter corresponding to a field input as the input data from parameters in the parameter storage means and outputting the selected parameter;data comparison means for checking match between the parameter output from the parameter selecting means and the input data;comparison result storage means; andcomparison result decision means;the comparison result storage means initializing 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 the comparison result decision means when there has been 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; andthe comparison result decision means storing ""match"" in the comparison result storage means when the storage content of the comparison result storage means and the comparison result of the data comparison means are ""match"".
