   The technology, called PCMOS (probabilistic complementary metal-oxide semiconductor VKMOP), was developed Palemom Krishna (Krishna Palem), professor at Rice University and head of the Institute of Progressive nanoelectronics with Nanyanskom Technological University (Nanyang Technological University, NTU).
The aim of the study are green calculation. Now a team of scientists led by Krishna Palemom and Kiat Seng Yeo (Yeo Kiat Seng), assistant professor of NTU and the head direction of electrical circuits and systems, Faculty of Mechanical Engineering, is seeking applications for PCMOS, where the application of this technology would perform the same functions, but consuming only a fraction of the required energy.
Probability of consumer electronics can be a base for energy-efficient devices - said Palem. For example, consumers can really make a difference, getting the opportunity to charge the phone every two weeks rather than every other day. In addition to the encryption system, called, among other applications, this technology can be used for computer graphics. Professor Palem explains that streaming video on a mobile phone does not need to be accompanied by a high-precision calculations. The small screen, combined with an ability to handle the human brain is not enough clear shots - and the resulting images look fairly even at about loyal calculations.
Natalie Kong Ji Hui (Natalie Kong Zhi Hui) of the NTU said that this technology is an important step toward a friendly environment green computing with the extremely high rates of energy. Unlike conventional structures, where the noise is a hindrance to our development of the noise plays the role of the kidney - a new technology of processing noise. Created microchip confirms the advantages VKMOP technology, which shows 30-fold reduction in energy consumption and 7 times higher speed than that of the modern CMOS designs.
In contrast, today`s silicon transistors become more and more vocal with a decrease in size, engineers have historically struggled with the increase in operating voltage to suppress noise and to ensure accurate calculations, increasing energy consumption. With the help of technology VKMOP variation characteristics of the noise is part of the structure and used as a source of achieving significant energy savings. We want to see a new generation of probabilistic nanoelectronics in mediasfere and medicine, information technology and consumer electronics. Successful development of this project will start for the long journey to introduce a new generation of green technologies at a lower price for the consumer - said Yeo.
According to Yeo, PCMOS can also be successfully applied to the cipher - Operation based on the generation of random numbers. This means that the chip is quite easy to incorporate into electronic devices, as in computer games, lotteries and cryptography required arbitrary computations. And all this in addition to the areas where statistical simulation, such as financial and economic projections, which will enable it to perform with greater precision.
The resulting chip is the result of studies of various designs of chips, launched in 2005. It is equally important that PCMOS sold on the basis of current CMOS technology, already used by manufacturers of microchips. Thus, to support PCMOS can use existing equipment, thereby reducing the cost of deploying new technology. The concept of development VKMOP will include a new generation of electronics based on the mathematics of probability. These opportunities will be in demand in areas such as risk analysis, perceptional neurobiology, nanoustroystva and calculations in the graphics and multimedia - said Palem.
The scientists hope that PCMOS-technology will be on the consumer market, a minimum of 4 years and could become a parallel CMOS-technology development area in the near future.
