Abstract
The invention relates to a method of coding and storing fuzzy logic rules, and to a circuit architecture for processing such rules. The method provides for at least one inference rule of the IF/THEN type, having a predetermined number of antecedent parts of fuzzy variables and at least one consequent part, to be dismembered and stored into memory words to allow subsequent processing using logic operators of the AND/OR/NOT type. The coding of rules and variables is effected sequentially. Thus, the occupation of memory locations can be minimized. Specifically, the rules are coded through a multi-word description, such that the number of words coding each rule is a varying number dependent on the number of antecedent parts in the rule.
