In the search for a fuzzy logic equivalent of the FPGA, the authors have developed the design for a programmable fuzzy logic controller chip which can accept up to 4 inputs, provide up to 12 programmable membership functions to fuzzify those inputs, and provide up to 8 programmable singleton values from which an output can be synthesized. Up to 64 rules can be evaluated simultaneously. The analogue modules which perform the fuzzification, rule evaluation and defuzzification operations are interconnected in a programmable fashion, modeled on the structure of FPGAs. This design will require an area of about 6mm2 in 0.8mm CMOS technology and draw about 9mA.
