thanks for the laugh, I was an FAE for Motorola back then and I remember when we had to promote this to customers, give out dev boards - or sell them. I dont recall any customer for micros ever caring about it at all. These days in the semi industry we would still be tracking the status that "design win" and your development board all the way to the landfill.

My assessment was similar to yours. It struck me of how marketing would design systems if given the task, more trial and error than structured design based on an understanding of the system.

I particularly liked this line from Abramovitch: "It comes down to sample rate versus computational complexity."

Sometime back I stumbled upon an article by Daniel Abramovitch at HP/Agilent. His presentation provides an interesting viewpoint of FL http://dabramovitch.com/pubs/fuzzy_acc_talk_2e.pdf

Examples of consumer applications of fuzzy logic often seemed to be better served with linear or analog solutions (in the winter, the cooler the house is, the harder you run the furnace and the air blowers). Deciding between low, medium, and high seemed artificial. Some examples do survive (dishwashers offer light, normal, and heavy wash options). Certainly the observations about computing power are also quite relevant - the fuzzy logic decisions typically are trivial compared with the computing power that is running idle.

The fundamental problem with fuzzy logic is that it comes up with a simple solution, but it is processor intensive and it isn't anywhere near optimal.

Yes Peter I think that is what was intended. It looks as though the actual line of text that I quoted has suffered from a word-for-word translation from the original German.

Fuzy logic based control could not extend various aplication areas due to uncertainty. With new dsp based cpus you need more certainty not uncertainty...

In grad school at Berkeley in the mid '80s, I was in Prof. Zadeh's Expert and Knowledge-Based Systems seminar for a few years, and he never once mentioned FL unless someone brought it up. In private, he would actively promote its' application to IR (i.e., search), even if it didn't quite fit. At one time (I'm too busy to check), there were at least two proper academic journals dedicated to FL, and now decades later there is at least an institutional echo of the movement in the Berkeley Initiative in Soft Computing (http://www-bisc.cs.berkeley.edu/BISCProgram/default.htm), which seems a bit like the Hair Club for Persians. Prof. Zadeh was a great guy, in the cosmopolitan/humanitarian/uber-nerd tradition.

My understanding of fuzzy logic is that it was a way to have a controller that did not have enough horse power, do the job. Since almost all of the devices today have more than enough power to do the job, fuzzy logic doesn't have much of a use.

NEXT UPCOMING BROADCAST
In conjunction with unveiling of EE Times’ Silicon 60 list, journalist & Silicon 60 researcher Peter Clarke hosts a conversation on startups in the electronics industry. One of Silicon Valley's great contributions to the world has been the demonstration of how the application of entrepreneurship and venture capital to electronics and semiconductor hardware can create wealth with developments in semiconductors, displays, design automation, MEMS and across the breadth of hardware developments. But in recent years concerns have been raised that traditional venture capital has turned its back on hardware-related startups in favor of software and Internet applications and services. Panelists from incubators join Peter Clarke in debate.
