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.

Abstract: A fuzzy computer which provides high speed fuzzy processing by executing fuzzy information processing in parallel. The fuzzy computer operates according to programs and data downloaded from a host system, and executes fuzzy information processing in parallel to process this information at high speed. The fuzzy computer comprises a single fuzzy processing controller which downloads and designates to control memory operational programs from the host system, starts fuzzy operations according to signals inputted to an instruction register, and informs the host system of its processing status through a status register. A plurality of fuzzy processing elements are connected in parallel to the single fuzzy processing controller through system buses, download fuzzy data from the host system to each built-in knowledge base and perform respective functions in parallel according to control signals from the single fuzzy processing controller.
