Auto Industry's Fastest Processor Is 128Mhz

Posted by kdawson on from the hot-in-here-or-is-it-me dept.

afabbro writes "GM stated that the 2011 Buick Regal will have the auto industry's fastest processor: 128Mhz, and 3MB of flash. 'Three meg of flash memory and 128MHz clock speed doesn't sound like a lot in terms of computing power until you consider the environment these controllers have to live in. Our controllers are made to operate reliably up to 260 degrees (127C) and down to -40 degrees (-40C) for the life of the vehicle.'"

    128MHZ for a rugged CPU for automotive use is a good thing, but clock speed is just one of many factors. TFA was a tad light on information and worded as an ad (which is to be expected from GM's press website), but other than just mentioning vague details and the fact that Freescale made it, this doesn't really mean much without factoring in other details.

    Will this mean the 2011 Regal will be leaps and bounds over the 2010? Yes. How much is debatable.

    Will this matter in the total scheme of automotive technology? Not really. ECMs have been improving each year, so the 2011 Regal may have a bump in the control CPU's clock speed, but perhaps some other car maker would have a different architecture in place (multiple modules controlling different functions such as PATS/antitheft, O2 sensor, fuel sensor [1], etc.)

    Will other car companies have improvements in their technology? Assuredly. Ford has some new engines going in the mainstream line of vehicles. Other vehicle makers may be bringing diesels to the US.

    The big question in all of this: Is there a car example I can go on here?

    [1]: I'm sure all cars in the US will eventually be going Flex-Fuel (talk about bumping gasoline from 10% to 15% is happening in some places here in the US), so having the circuitry in place to handle varying amounts of ethanol will be crucial.

      This progression is to be expected. But the thing people should be asking is: does the new Buick ECM have an interface exposed that third parties can build readers for? Is there an assessable API? Probably not, so all this power will only be available to dealerships.

      Other plants can be used to make ethanol, but it's not being done widely. When cellulosic ethanol is workable on a mass scale, then the value of ethanol production might change to something that's of a net benefit to society.

      All agriculture not based on returning the shit to the fields is inherently harmful. It amounts basically to hydroponics in a dirt (not soil) medium. Feeding humans without maintaining the soil has already destroyed much of the planet's arable land to the point where there would be worldwide starvation without exports from the Americas or acres of land dedicated to greenhouses and hydroponics in the nations where the food is eaten. All of which, just like the so-called "Green Revolution" farming used by big agribusiness today, is based on oil; synthetic fertilizers, synthetic pesticides, all the plastic that it's all made of, and all the energy to run it around. Topsoil-based fuels will lead us directly to a future where only the rich can afford to eat real food, which will be produced on hillside farms in locations too remote to factory-farm.

      Consequently, as you say, only cellulosic ethanol is of a benefit to society. The analyses of ethanol's net energy value don't even take damage to the soil into consideration.

    "On the other hand, it also weighs twice as much as the MG and handles like it, so good luck avoiding an accident that he could."

    The Corolla probably handles better. See this article about an autocross race between an 2003 Honda Odyssey, a 60's Porsche 356 and a 60's Jag XKE.

  3. Sounds like plenty to me... by commlinx · · Score: 3, Interesting

    Three meg of flash memory and 128MHz clock speed doesn't sound like a lot in terms of computing power

    Guess that depends on your point of view, a car travelling 360Km/Hr is travelling 100m/s, so in a millisecond travels 10cm or about 4 inches. Assuming one instruction per clock cycle you can do a lot of useful stuff with 128,000 instructions, or put another way probably about one million for every revolution of the wheel

    3MB of FLASH is huge as well when you aren't loading a lot of crap like multimedia, not that it would run Linux but I just took a look at the last kernel I built for an embedded platform and it came in under 2MB with quite a generous set of modules loaded.
