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
fuzzy
TECH 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
