2. 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

3. 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
