Abstract
A fuzzy processor which can be programmed and expanded is disclosed. The fuzzy processor has a membership function I/O circuit for inputting and outputting a plurality of membership functions respectively corresponding to each one of a plurality of features of each one of a plurality of standard patterns. A feature decoder receives a to-be-recognized pattern having a plurality of input features for generating a plurality of feature values. A membership function generator stores the plurality of membership functions and receives the plurality of feature values to generate a plurality of current-type membership degrees for the plurality of input features corresponding to the plurality of standard patterns respectively. A plurality of accumulators receive the plurality of current-type membership degrees respectively for generating a plurality of synthesis membership degrees. An expandable synthesis membership degree comparing circuit is provided for receiving the plurality of synthesis membership degrees from the plurality of accumulators to output said plurality of synthesis membership degrees as well as the corresponding standard patterns in an order of magnitude.
