Abstract
A minimum-maximum computation circuit (5) includes a circuit (10) for detecting an order of magnitude of the input label's grades and a circuit for executing a minimum-maximum calculation (41, 42, and 49) according to an order of the magnitude of the input label's grades. The minimum-maximum computation circuit includes a rule memory (20) for storing rule-associative-bit-groups which include a valid/invalid bit for each of the coded rules. Each of the coded rules include an arrangement of valid/invalid bits for indicating whether each of said input labels is included or not in the antecedent of said each of rules. The minimum-maximum computing circuit further includes a weighting factor circuit (63) for providing weighting factors in their magnitude order to be applied to selected fuzzy rules.
