Fuzzy Logic Inference Processor for Real Time Control: A Second Generation Full Custom Design,
Hiroyuki Watanabe, W.D. Dettloff · NASA STI/Recon Technical Report N · 1986
Abstract : The VLSI implementation of a fuzzy logic inference mechanism allows the use of rule-based control and decision making in demanding real-time applications such as robot control and in the area of command and control. The full custom CMOS VLSI is described. The chip is second generation of the design. It has several design features which make the use of this chip realistic. These features include reconfigurable architecture, on-chip fuzzification and de-fuzzification, and memory and data-path redundancy. The chip consists of 614,000 transistors of which 460,000 are used for RAM memory. Keywords: Automatic process control systems; Chip architecture.
