Abstract
A switched-current fuzzy processor for pattern recognition is provided, which is specifically designed to operate in current mode for high performance. The switched-current fuzzy processor includes means for decoding a feature input into a set of binary feature signals; an array of MFGs, coupled to the decoding means, for obtaining a set of current outputs whose magnitudes are proportional to the values of the feature signals respectively; weight-adjusting means, coupled to the MFG array, for applying a predetermined weight factor in binary form to the output currents from the MFG array; summing means, coupled to the weight-adjusting means, for summing up each set of currents from each column of the MFGs in the MFG array to thereby obtain a total value for the currents therefrom; and a maximum-value determination circuit, coupled to the summing means, capable of obtaining the one of the currents with the maximum magnitude from the summing means. The foregoing switched-current fuzzy processor features that the circuits in the simulation unit are all based on the switched-current mode of operation without the need to use current-to-voltage conversion means, thus allowing simplified c…
