Engineers at the University of Michigan (University of Michigan) reported about the invention of the most economical microprocessor that consumes 30,000 times less power in standby mode and 10 times less than in normal mode, than any commercially available chip.
With a record-breaking performance of energy consumption, the microprocessor, dubbed Phoenix (Phoenix), designed for use in ultra-touch devices such as medical implants, environmental sensors and surveillance equipment.
Chip consumes only 30 PW (10-12 watts) of electricity in standby mode. In theory, the energy of the battery for a watch would be enough for 263 years of the Phoenix.
The size of the microchip - one square millimeter. But it is not its main advantage, because Many modern sensor devices operate on such a chip size. The main achievement of engineers is that, due to its cost, the Phoenix for quite a tiny thin-film battery size is not greater than the microprocessor itself.
In most cases the batteries much more than they powered microprocessor, which increases the size and cost of the system. The battery in the laptop, for example, about 5000 times greater than the microprocessor, and that for only a few hours.
Low power consumption possible to reduce the size of the battery and the system as a whole. For its size, the device is built on a similar chip (including the battery) will be 1000 times smaller than the smallest known to date sensor.
Due to its size and cost, sensor-based systems such chips can be used in various fields of human activity.
For example, we put a microchip biomedical sensor to control intraocular pressure in patients with glaucoma. Engineers also suggest that such chips can "spray" around to create an almost invisible network of sensors that will monitor air or water, as well as to detect motion. They can be mixed into the concrete in the future to monitor the structural integrity of new buildings and bridges. In addition, it is possible to implement such chips pacemaker that could receive more detailed data on the state of health of the patient.
To achieve such a low level of energy consumption, Phoenix engineers focused on standby in which the sensors spend more than 99% of the time. Sensors "wake up" just for a moment, at regular intervals, to make the necessary calculations. The main mode of the system - a dream. A low power timer from time to time "wakes" Phoenix every 10 minutes on 1/10 of a second, so he performed a set of 2000 instructions and sank back into slumber.
