We describe a digital architecture to evaluate fuzzy inferences. This architecture is based on a novel systolic structure in the field of fuzzy processing that is called multilevel systolic approach. Its main features are: high throughput, perfomance independent of the fuzzy model size supported, high flexibility to resize the parameters of the design, max-min inference, and capability for a considerable amount of complex rules without loss of efficiency. The circuit development has been carried out by using a VHDL simulator, with ES2 1um standard cells, and its results has given a perfomace over 10 mega fuzzy logic rule base inferences per second.
