A 30-Picowatt Processor For Sensors

Roland Piquepaille writes "University of Michigan (U-M) researchers have developed an ultra low power microchip which 'uses 30,000 times less power in sleep mode and 10 times less in active mode than comparable chips now on the market.' It only consumes 30 picowatts in sleep mode, which means that a simple watch battery could power the chip for more than 200 years. Of course, this is not a processor for your next computer. It is designed for sensor-based devices such as medical implants, environment monitors or surveillance equipment. However, the design is very clever." Roland's blog has some more information, including a die picture of the chip, known as the Phoenix.

  4. 10 Times Less? How is that possible? by b4dc0d3r · · Score: 2, Funny

    I have one item at 10 units of electricity. I have another item using 10 times less electricity. So it uses (10 units * 10 = 100) 100 less units of electricity, for a total of -90 units.

    Does that make any kind of sense to any of you?

    Wouldn't you want to say 1/10th and 1/30,000th? Or even be cool and say "one order of magnitude" or even "5 orders of magnitude and a third applied to the result".

    (please disregard the less/fewer issue here, one thing at a time)

    No, it runs an age old Operating System called "Main Loop".

    You connect it with Denon's ethernet cable, to get all the most processing power possible.
