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.
