VLSI fuzzy chip and inference accelerator board systems

The architecture and operational features of a VLSI fuzzy logic inference processor are described. Also described are the architecture and associated high-level software of two VMEbus-board systems based on the fuzzy chip. The VLSI implementation of a fuzzy logic inference mechanism allows the use of rule-based control and decision making in demanding real-time applications. The CMOS chip consists of 688000 transistors, of which 476000 are used for RAM memory. In addition to operating in a robot, the single chip board is installed on a Sun-3 workstation for further research and software development. >
