Abstract

An 8b Fuzzy Coprocessor (FC) is presented that has eight programmable fuzzy algorithms and up to 256 inputs, 64 outputs and 16,384 rules. The 6.4mm2 chip fabricated in 1.0$\mu\textrm{m}$ CMOS technology can be used as a stand-alone device or as a macrocell for microcontrollers. Operating at 20MHz crystal frequency, it has a peak performance of 7.9M rules/s. Perspectives of future FC generations are also outlined, including a 12-16b resolution, additional fuzzy set operations, and optimized inference and defuzzification strategies.
