Abstract

An arrangement (apparatus and method) using fuzzy logic controls a plurality of devices in response to inputs. The time-division-multiplexed input signals are demultiplexed and fuzzified according to predetermined fuzzy sets. The fuzzified input signals are input to an asynchronous multipath feedforward network which determines a minimum rule term for each rule processed. The multipath feedfoward network is dedicated to processes the fuzzified input signals in parallel and to determine the minimum rule term using a minimum amount of circuitry. Parallel processing of the fuzzified input signals is accomplished using a plurality of minimizing elements. Significant Bits of minimizing element output signals are successively compared in a NAND tree and a resulting output is fed back to the input of each minimizing element. Upon stabilization the resulting output is the minimum rule term.
