<p>PURPOSE: To detect the congruence of two data patterns at a high speed. CONSTITUTION: A pattern matcher 10 includes an error pattern generator 12, an encoder 14, adders 16-18 and a congruence detector 20 and also optionally includes a second encoder for encoding an addition value generated by the adder 18. The error pattern generator 12 compares the correspondence symbols of two 'P' symbol data patterns so as to discriminate whether the patterns are congruent or not. A symbol is bit and, therefore, the pattern is P-bit length. The error pattern generator 12 compares more than three corresponding symbols and discriminates whether or not the plural patterns are congruent, for example.</p> |
