Fuzzy Processing Implementation in Dedicated Digital Hardware The paper presents a concept of digital circuit dedicated for fuzzy processing with numerical inputs and outputs. Partially concurrent and pipelined data flow provides high performance, with relatively low dependence on particular algorithm complexity. Sample design with triangular fuzzy sets, rule strength calculation (minimumapproach) and defuzzyfication by weighted sum of fuzzy sets centers was implemented in VHDL, verified and synthesized for FPGA. Floating point arithmetic was applied, including dvision performed by dedicated synchronous machine. All modules were prepared for easy reuse/redesign.
