The design of a programmable fuzzy logic controller chip

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 synthesised. Up to 96 rules can be evaluated, but not all at once-logic is built in to select at any instant only the rules which are firing.
