38. An electronic controller, comprising: means for receiving an input which indicates one of a finite number of points; a memory section for storing predetermined values of the membership functions wherein the memory section stores, for each of the finite number of points, an indication of and the value of only those membership functions for which the degree of membership of the point is not zero; a calculating section for performing the fuzzy logic inference operations; and a buffer section, between the memory section and the calculating section, for regenerating effective values of the membership functions to extract predetermined weights involved in the rules which configure the inference operations.

An electronic control device of claim 38, wherein the buffer section comprises a program memory, in which all the rules for the inference operations are stored, and having an output indicative of a membership function; and a comparator, for comparing bits of a part of the memory word output from the memory section and related to the membership functions, with bits of a reference memory word contained in the program memory.
