A pipelined fuzzy reasoning processor with software development system and its application on the crane control problem

Fuzzy reasoning processors have been employed in many commercial and industrial applications. A high-performance pipelined, single-instruction-stream, and single-data-stream architecture of fuzzy reasoning engine has been designed. Based on this architecture, the proposed VLSI processor for embedded real-time fuzzy logic applications was fabricated in an 0.8-μm CMOS technology. Its computation power can reach 2.5 million fuzzy logic inferences per second (MFLIPS) at a system clock of 20 MHz. In order to efficiently realize fuzzy applications, a software development system under Microsoft Windows has also been designed. For the purpose of showing its effectiveness, we have carried out the experiments to successfully control the crane system. Experimental results have shown the efficient cooperative control of the proposed fuzzy reasoning processor with software development system and can be contrast with conventional computer software interface control
