Fuzzy Logic Implementation in Embedded Control 1980 The first software implementations of fuzzy logic on microcontrollers were highly inefficient (~1 sec. on 8051/12). 1990 One group of companies sought hardware-accelerated solutions (First 8-bit fuzzy copcocessor FLC110 by InfraLogic/VLSI, developed at Rockwell). 1990 Another group of companies sought software-accelerated solutions and developed fuzzy-microkernels for standard MCUs (Intel and Inform). 1992 The second generation of fuzzy processors integrate fuzzy acceleration on standard microcontrollers (First 16-bit fuzzy integrated processor FUZZY166 by Inform/Siemens). 1993 Fuzzy microkernel technology in fuzzyTECH MCU Editions satisfies performance goals (~1 millisecond on 8051/12) and becomes available for most MCUs. 1996 Motorola announces the world’s first standard MCU with fully integrated fuzzy hardware acceleration. 68HC12 d,fcnas.dfknj aösl.dkjf ölaskdjf öaslkjdf öaslkdfj as df as df a sdf asd f as df asdf df asdf Nearly All of Today’s Embedded Applications Use Software Implementations with Fuzzy Logic! © INFORM 1990-1996 Slide 2

Fuzzy Instruction Set Enhancement 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 d,fcnas.dfknj aösl.dkjf ölaskdjf öaslkjdf öaslkdfj as df as df a sdf asd f as df asdf df asdf The Performance of a Dedicated Fuzzy Hardware Solution Without A Premium Cost! © INFORM 1990-1996 Slide 3
