Abstract
The paper describes a general-purpose board-level fuzzy inference.engi ne intended primarily for experimental and educational applications. T he components are all standard TTL integrated circuits (7400 series) a nd CMOS RAMs (CY7C series). The engine processes 16 rules in parallel with two antecedents and one consequent per rule. The design may easil y be scaled to accommodate more or fewer rules. Static RAMs are used t o store membership functions of both antecedent and consequent variabl es. ''Min-max'' composition is used for inferencing, and for defuzzifi cation, the mean of maxima strategy is used. Simulation on VALID CAE s oftware predicts that the engine is capable of performing up to 1.56 m illion fuzzy logic inferences per second.
