Abstract

Two fuzzy microprocessors have been developed as VLSI chips. One is an if-part processor with single instruction, multiple data (SIMD) architecture, and the other is a then-part processor with logic-in-memory. The system configuration using the chips can execute fuzzy inference for if-then fuzzy rules. The speed of inference including defuzzification is 7.5 M fuzzy logical inferences per second (FLIPS), and the system can process 960 rules and 16 input and output variables. The rule format can be easily changed by rewriting the instructions stored in the memory. The processors require no external memory since the knowledge-base can be stored in the internal memory
