Fuzzy hardware synthesis with generic LR fuzzy cells

A novel primitive cell structure, called the LR fuzzy cell for hardware realization of fuzzy reasoning or other fuzzy computations is proposed. An LR fuzzy cell is an integral unit encapsulating an LR fuzzy set and a basic fuzzy operation like implication or an arithmetic operation. Using the LR fuzzy cells, we can synthesize high-performance fuzzy systems including fuzzy ASICs and general-purposed fuzzy processors in a fast and systematic way. The synthesized fuzzy systems inherently possess parallel inference ability. The system expandability and modifiability are also warrantable. The proposed generic LR fuzzy cells are implemented with current mode analog technology. By this technology, a fuzzy processor design based on this cell structure possesses the characteristics including small circuit area, high performance, low power dissipation, etc.
