Abstract :
A novel Josephson fuzzy processor using SQUID gates is proposed, and the simulation results are illustrated to show how a high-performance fuzzy processor can be realized by taking into consideration of advantages of Josephson devices. The features of the proposed processor are very simple construction, very high-speed operation, and ultra-low power dissipation. The principles of constructing a fuzzy processor using SQUIDs are described in detail, and the simulation results for the essential circuit of the fuzzy processor (which is composed of more than one hundred SQUIDs) are illustrated. These results show that Josephson fuzzy processor with four rules and sixteen input levels can perform the function in less than 1.3 ns, and can perform the fuzzy inferences 0.79×109 times per second
