A fuzzy inference coprocessor using a flexible active-rule-driven architecture

A type of fuzzy inference coprocessor in which active rules can be detected from a set of arbitrary fuzzy rules was designed. In this architecture, referred to as the flexible active-rule-driven architecture, active rules are detected for various fuzzy rules and for various membership functions. The fuzzy inference scheme and the concept of active rules are reviewed. It is shown that active rules can be defined for different fuzzy inference methods. The main features of the flexible active-rule-drive architecture are described. The basic function of the coprocessor was confirmed using a logic simulator. Other features of the coprocessor, such as arithmetic-unit calculation of membership grades, are also discussed. The circuit simulations of the coprocessor and its implementation are outlined
