Have developed the chip with record energopotrebleniem

Scientists from University of Michigan (University of Michigan, the USA) have developed a microchip consuming in a mode of expectation in 30 thousand of time less of electric energy in comparison with similar modern chips and in 10 times less — in an active mode, informs Cnews. Energopotreblenie Phoenix Processor in an expectation mode makes 30 pikovatt (pikovatt — 10-12 Vt — or one trillionth watt). Theoretically, a charge stored in a battery for a watch, will be enough for a food of such chip within 263 years.

he new processor, which size makes 1 sq. mm, is planned to use in modern measuring devices, the medical equipment, etc.

Together with the chip scientists had been developed the battery for its food. Its size is comparable to the size of the chip. According to developers, creation of so small independent system — the big achievement. For comparison, the size of the storage battery of the laptop in 5 thousand times exceeds the size of the processor established in it. Thus time of independent work of the computer makes all some hours. «Low energopotreblenie has allowed us to reduce overall dimensions of an element of a food. Our system in one thousand times less than any known sensor control for today», — speaks professor David Blau (David Blaauw).

According to scientists, modern gauges conduct more than 99 % of time of the work in an expectation mode. This the fact also has been taken for an invention basis. «The greatest part of time gauges are inactive, therefore to reduce energopotreblenie the chip in this condition was our prime purpose», — one of developers, Dennis Silvestr (Dennis Sylvester) is divided. The processor automatically "wakes up" each 10 minutes for 1/10 seconds for which has time to execute 2 thousand commands, including reception of the new information from the gauge, processing and storing. Consumption decrease also has been reached at the expense of the new shutter completely blocking course of a current in a mode of expectation. The chip while memory remains energised is thus disconnected only.

Processor Phoenix can be used in gauges for measurement of durability of designs, automobile and railway bridges, in kardiostimulyatorah, in movement gauges, metres of water etc. the Design of the processor will be demonstrated on a symposium of engineers of University of Michigan on June, 20th, 2008
