Abstract

The subject of the application relates to an arrangement comprising a rule decoder, a rule evaluation unit and a unit for forming selection signals, to which arrangement, from a fuzzification circuit, a minimum and a maximum number of relevant linguistic values of a respective input variable and values . . . me of membership functions of linguistic values whose numbers lie between the minimum and maximum number, and from a knowledge base memory numbers for linguistic values, prescribed in a plurality of rules, of the respective input variable, can be fed, and processing of these fed numbers and values can be executed simultaneously in parallel with processing of the respective next input variable in the fuzzification circuit. An advantageous refinement of the subject of the application also permits defuzzification running partly simultaneously in parallel with the rule decoding and evaluation.
