Intel would be this week at the International Solid-State Circuits Conference, new developments in the field of highly energy-efficient processors. Also demonstrates the company has a Atom cpu with a ge lwa-in wi-fi radio.
The with wi-fi comprehensive 32nm-Atom-processor was named Rosepoint. Since only digital components are used, the necessary parts of a piece of silicon with two Atom cpu’s to share. The wi-fi components of the prototype will require only two voltages, in contrast to the multitude of tensions that analog components require. Intel would not be in wi-fi; also the gsm and derivative signals necessary components would in future Atoms ingrained. According to Intel cto Justin Rattner should lead to cheaper and more fuel-efficient chips.
Rattner demonstrates on the ISSCC, again, the Claremont processor, that earlier on IDF was shown. This on the Pentium architecture, but on 32nm produced processor makes use of so-called near threshold voltage technology. This would mean that processors with very little voltage, about 280mV, at the low frequencies can operate, while the speed is increasing with higher voltage. A pc would with that technology is never completely shut-down need be, but only slowly, in stealth mode continue to work.
The ntv-technique was IDF with an x86 processor will be shown, but Intel wants during ISSCC wider extract. The LVT technique must be applied to a simd engine, or processor for graphics chips. The simd engine was on 22nm baked and come with Intel’s trigate transistors, which are also Ivy Bridge transistors are used. The graphics processor would still function with a minimum of 280mV, just as the Claremont.
Intel also demonstrates memory chips at low voltages work. The sram memory has been on 22nm produced. Intel also shows other techniques, including fast and efficient cache memory for processors and a floating point unit with variable precision of 24, 12 and 6 bits. The lower precision leads to a reduction in the demand for energy and the fpu can also of Intel’s NTV technology use.
