fuzzyTECH® 4.0
	MCU-320 Edition
by Inform Software Corporation

Software Overview

Fuzzy logic empowers system design with new, innovative functions. Complex system design is 
rendered quickly and existing solutions can be achieved using state-of-the art development tools. 
With fuzzyTECH, Inform provides a complete graphical development tool, that enables you to specify, 
design, optimize, and implement an entire system by simply point and click. Applications of fuzzy 
logic technologies range from industrial automation and embedded control to data analysis and 
decision support. As each applicational area requires different target hardware platforms, 
different implementation techniques must be employed. 

Features and Benefits

•	fuzzyTECH TMS320 supports all digital signal processors (DSP) of the TMS320 family of Texas 
Instruments (not `C1x and `C8x families).
•	The fuzzyTECH MCU-320 Edition uses an assembly code library that has been designed in close 
cooperation with the silicon manufacturer. The fuzzyTECH MCU-320 Edition supports only fuzzy 
technologies that are relevant for embedded-control designs on the special hardware platform. To 
customize fuzzyTECH for specific applicational areas, add-on modules are available.

Processor and System Requirements

•	No specific TMS320 peripheral devices are required. All Editions and Modules of fuzzyTECH run 
under MS-Windows 3.1x or MS-Windows 95. Minimum requirement for the development software is a 
386-class PC with 10-MB free hard disk space, 4-MB RAM, and a 3½" disk drive.

Usage Limitations or Performance Considerations

•	To benchmark the performance of fuzzy-logic implementations, typical configurations that stem 
from industrial applications show computational speed and memory requirements.
•	A simple fuzzy logic position controller using 7 rules, 2 inputs, 1 output requires an average 
computation time of 0.020 ms, worst case 0.022 ms on a test device: TMS320C52, ext. ROM, 20-ns 
instruction. The controller uses ms 0.85-kB ROM 
54-byte RAM.
•	A parameter estimator in an ABS System with 80 rules, 3 input, 1 output, and rules weights 
require 0.039 ms/0.049 ms average/worst case computation time and 1.8-kB ROM/70-byte RAM on the 
same device.
•	An intervehicle dynamic controller using 500 rules for 8 inputs, 4 outputs, and rules weights can 
be computed in 0.146 ms/0.188 ms and requires 5.7-kB ROM, 218-byte RAM.

Company Background and Contact Information

For over a decade, Inform has used fuzzy logic in turn-key intelligent control systems. To support 
these in-house applications, fuzzyTECH was developed as an internal productivity tool in 1988. In 
1991, fuzzy-TECH was introduced to the European and Asian markets. In 1993, Inform's U.S. 
subsidiary, Inform Software Corporation, introduced fuzzyTECH to the U.S. market.
To optimally support embedded applications, Inform has teamed up with leading semiconductor 
manufacturers and developed the fuzzyTECH MCU Editions. This enables standard microcontrollers to 
run fuzzy logic systems. The code space efficiency and computational speed of the fuzzy-TECH MCU 
Editions' code generators allow the enhancement of most embedded system designs with fuzzy logic.
Inform maintains fuzzyTECH at the leading edge of fuzzy technologies. Inform's NeuroFuzzy Module 
was the first integration of neural net technology and fuzzy logic applied on an industrial scale.
Besides development and marketing of fuzzyTECH design tools, Inform is the world's largest supplier 
of fuzzy logic consulting. European clients are supported from Inform's head office in Aachen, 
Germany; U.S. clients are supported by Inform Software Corp., Evanston, Illinois.
Fuzzy Logic and NeuroFuzzy Applications Explained by Constantin von Altrock, Prentice Hall, ISBN 
0-1336-8465-2, shows how to design technical fuzzy logic applications and contains a demo of the 
fuzzyTECH software with 10 control system simulations to experiment. It also explains the use of 
fuzzy and NeuroFuzzy techniques in 70+ case studies.
