At the same time, Ethernet has gained momentum, because it’s a fast, mature technology with high production volumes in the computer industry. "Ethernet has a certain beauty compared to MOST," Reger told us. "It's not proprietary. And you have a few hundred thousand man-years of development in TCP/IP-based systems around the world and in all sorts of applications."
The auto industry's idea is to leverage the computer industry's enormous Ethernet know-how.
The concept is apparently catching on. Freescale Semiconductor recently teamed with BMW on the development of a 32-bit Ethernet-based microcontroller for use in surround-camera parking-assist systems. And more companies, including Daimler AG, are said to be on the verge of joining the SIG.
"The industry is begging us to develop Ethernet silicon," Reger says. "The automakers in China, Korea, and the US who did not already have MOST in their vehicles are highly interested in Ethernet."

Even after years of reading about the incredible advances made in automobiles, I am still amazed at what the car companies are coming up with. When I was younger and my parents put the car on "cruise control," I thought it meant that the car knew where we were going and would just take us there by itself. Based on all the fascinating (at least to me) stories I've been reading lately, I'd say that might not be so far-fetched after all!
Chuck - How much of this slow adoption rate do you believe is due to regulations and entrenched processes in the automobile industry? Having worked on the research and development side of the automobile industry I know that they are very innovative and develop cutting-edge tools used for design and testing -- all while the production vehicle is outfitted with a cassette tape deck and a bicycle brake cable actuator for the fuel door.
Replacing the spools of copper with multiplexed twisted pair would have an instant effect on fuel economy. Is it because "that is not how it is done" or an automated assembly line that cannot accommodate radical change? I suspect that it is not due to insufficient technology.
Having come from the traditional IT world where Ethernet has long been a standard, I suppose I have a particular bias. That said, Chuck, I'm wondering why the automotive makers and other industry sectors have been hestitant to spec Ethernet in the past since it's such a well-proven technology? What advantages did the MOST technology you talk about in the article have over Ethernet and how has that changed now?
Design News readers spoke loudly and clearly after our recent news story about a resurgence in manufacturing -- and manufacturing jobs. Commenters doubted the manufacturers, describing them as H-1B visa promoters, corporate crybabies, and clowns. They argued that US manufacturers aren’t willing to train workers, preferring instead to import cheap labor from abroad.
Using wireless chips and accessories, engineers can now extract data from the unlikeliest of places -- pumps, motors, bridges, conveyors, refineries, cooling towers, parking garages, down-hole drills and just about anything else that can benefit from monitoring.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
