ABSTRACT:
A circuit (14) to evaluate a plurality of fuzzy logic rules as executable instructions in a data processor (310). A first instruction retrieves a fuzzy input value from memory (32) and stores it in an accumulator (58). A second instruction retrieves a second fuzzy input value from memory (32) and compares it to the fuzzy input value stored in the accumulator (58). The minimum value of the two fuzzy input values is then allowed to remain in the accumulator (58). Another program instruction retrieves a fuzzy output value from memory (32) and compares it to the value in the accumulator (58). The maximum of these two values is then determined by the instruction and this maximum value is then stored in memory (32).
