ABSTRACT:
A fuzzy operation apparatus which can supply various fuzzy operators by combining basic operators provided by hardware with microprograms, performs fuzzy operations in parallel by connecting a plurality of fuzzy operation portions using a network, and performs parallel defuzzification of the result of fuzzy operations stored in the fuzzy operation portions throughout the network. The present invention establishes a network between fuzzy operation portions, performs fuzzy operation in parallel at a plurality of fuzzy operation portions, and defuzzifies each element of a fuzzy set dispersed and stored in the fuzzy operation portions such that defuzzification speed is fast. Also, since there is no need for an exclusive defuzzification processor, the cost of the system is low.
