ABSTRACT:
In a pattern recognition apparatus constituted by a one-chip LSI (large scale integrated), product-sum calculations are performed between an input pattern to be recognized and a plurality of reference patterns by a product-sum circuit. The plurality of reference patterns are stored in an external memory used as a dictionary. The similarity values obtained by the product-sum calculations are subjected to floating processing in a floating circuit. The similarity values, which have undergone floating processing, are sorted in the order of larger magnitudes. The sorted similarity values are read out by a host CPU (central processing unit).
