Fuzzy Logic Implementation in Embedded Control

Nearly All of Today’s Embedded Applications Use Software Implementations with Fuzzy Logic!

1980 1990 1990 1992 1993 1996 The first software implementations of fuzzy logic on microcontrollers were highly inefficient (~1 sec. on 8051/12). One group of companies sought hardware-accelerated solutions (First 8-bit fuzzy copcocessor FLC110 by

InfraLogic/VLSI, developed at Rockwell).

Another group of companies sought software-accelerated solutions and developed fuzzy-microkernels for standard MCUs (Intel and Inform). The second generation of fuzzy processors integrate fuzzy acceleration on standard microcontrollers (First 16-bit fuzzy

integrated processor FUZZY166 by Inform/Siemens).

Fuzzy microkernel technology in fuzzyTECH MCU Editions satisfies performance goals (~1 millisecond on 8051/12) and becomes available for most MCUs.

Motorola announces the world’s first standard MCU with fully integrated fuzzy hardware acceleration. 68HC12

The Most Efficient Implementation of Fuzzy Instruction Sets Is Within the MCU’s ALU One Instruction Set for the Complete Fuzzification of a Membership Function One Instruction Set for Complete Computation of Rule Inference for an Entire Rule Block One Instruction Set for Complete Defuzzification About 10x Faster Than a Aoftware Implementation on the Same ALU About 1/5 Code Space Compared to Software Implementation on the Same ALU No Interfacing Overhead
