Intel Introduces ‘Atom’ Brand For Its Innovative Microprocessors.
Intel Corp couldn’t have chosen a better name for the latest family of low power microprocessors - “Atom”, with two versions coming up sometime this quarter, namely what was previously known as Silverthorne and Diamondville.
Intel’s smallest microprocessors are especially designed for mobile Internet devices (MIDs) – Silverthorne, and a new class of low-cost Internet-centric computers named “netbooks” that will become available later this year – Diamondsville. The low cost computers will have an estimated price of $250.
“This is our smallest processor built with the world’s smallest transistors,” said Intel Executive Vice President and Chief Sales and Marketing Officer Sean Maloney in a statement. The new chips will be based on Intel’s 45nm cutting-edge technology, will have a thermal design power (TDP) specification in 0.6-2.5 range and scale to 1.8 GHz, depending on the customer’s needs.
“This small wonder is a fundamental new shift in design, small yet powerful enough to enable a big Internet experience on these new devices,” Maloney also said. “We believe it will unleash new innovation across the industry,” he added.
The California-based company strongly believes that the Intel Atom processors have great revenue potential in consumer electronic devices, embedded applications and thin clients.
Intel also announced the Intel Centrino Atom processor technology brand for MIDs, formerly known as “Menlow”. This Intel Atom processor - a low-power companion chip with integrated graphics – will support Wi-Fi, Bluetooth, WiMax, GPS and will have a lighter, thinner design.
The Intel Atom processor is designed for small, low-power devices, while maintaining the Intel Core Duo 2 instruction set compatibility consumers are accustomed to, measures less than 25 mm², making it the smallest and lowest power processor yet.
“Soon, you will see the Intel Centrino Atom brand on handheld devices that can bring an amazing internet experience in a device that fits in your pocket. You’ll see the Intel Atom processor powering a growing category of devices aimed at delivering affordable, Internet-centric uses”, wrote Brian Fravel Intel Director of Marketing, Brand Strategy, on the company’s blog.
Intel introduces the Atom processor
you thought the Intel processor inside the MacBook Air was small, think again. We had anticipated that Intel was going to launch a new line of low-power processors today, and they did so in the form of the new Atom processor, which according to the Santa Clara-based company is by far the smallest processor ever built by them.
The chips previously codenamed Silverthorne and Diamondville are based on an entirely new architecture and have been designed from the ground up to consume as little power as possible. Intel plans to target two main markets: with Silverthorne they hope to get inside the so-called 'Mobile Internet Devices' (MIDs). The more powerful and a bit more power hungry Diamondville will be targeted at small form factor laptops like the Asus Eee PC.
The Atom will be manufactured on an 45nm process and will carry a TDP specification in the 0.6-2.5 watt range - which is minuscule compared to a mobile Core 2 Duo's 35w TDP. Though comparing these CPUs' performance output would make no sense at all since they are aimed at completely different markets, the Atom is still a fully working x86 processor. To give you a better idea of how small these CPUs are, here's a promotional video from the Intel Mobility team blog.

A highly specialised computer modelling technique championed at The University of Nottingham has been instrumental in the design of a revolutionary new swimsuit which is now being hailed as the fastest in the world.
Dr Herve Morvan, a lecturer in fluid mechanics in the School of Mechanical, Materials and Manufacturing Engineering is working as an advisor to the AQUALAB, Speedo's competition research and development department, responsible for the development of Speedo's new LZR Racer swimsuit. Rick Sharp, professor of exercise physiology at Iowa State University collaborated with Dr. Morvan in the research.*
Within a week of its launch athletes wearing the new swimsuit had broken three world records.
Speedo harnessed the expertise of NASA and a number of international research institutes and industrial partners such as ANSYS, one of the world's leading engineering simulation software providers, to create the new suit.
The team at Nottingham specialises in Computational Fluid Dynamics (CFD), the computer modelling of fluid flow. The technique is rapidly developing in its technology and applications and can cut design times, increase productivity and give significant insight to fluid flows. (ANSYS is the CFD partner and provider.)
Dr. Morvan said, "CFD is used to help us gain an idea of the sources of skin and form drag. Skin drag is inherent to the material properties over which a fluid flows and to the local flow conditions (speed in particular) as it is induced by the local velocity gradients (on your body, the water velocity is 0 m/s; away it is faster; the gradient creates a shear due to the viscous property of the fluid)."
Form drag is due to the presence of one's body travelling through the fluid, and what is desirable is to make the flow path as smooth and undisturbed as possible. Dr. Morvan said, "With CFD analysis we were able to use the compressive properties of the suit to make the swimmer as hydrodynamically efficient as possible; some simulation were also used to help train/educate swimmer in fact, highlighting the effects of one's cap or finger positions on one's performance."
CFD also has other applications. It is commonly used for analysis, for example, in the Rolls Royce University Technology Centre which specialises in research for the aeronautics industry, and for many other applications relating to the energy, biomedical and sports sectors. As well as engineers, experts in the School of Mathematical Sciences and the School of Physics and Astronomy develop and use numerical modelling techniques of fluid flow to provide insight in fluid problems ranging from the atomic scale to that of the universe.
In this research, Speedo AQUALAB scanned over 400 athletes and obtained the scan for a series of top athletes. Using CFD analysis Dr Morvan and his team were able to pin-point areas of high friction on the athlete's body. With this information designers were able to position low friction fabric, exclusively developed by Speedo, in the right locations.
Dr Morvan, a lecturer in fluid mechanics, said: “CFD enabled us to use the compressive property of the suit to shape the body as ideally as possible, taking into account the physiological and bio-mechanical requirements of the athlete.”
The new suit has 5 per cent less drag than Speedo's 2007 suit, the FS Pro, which saw swimmers break 21 world records.
Analysis by Dr Morvan and his team at The University of Nottingham was carried out in collaboration with flume work at the University of Otago, in New Zealand and fabric tests by NASA.
Dr. Morvan added, "We also interact with physiologists (to take into account the athlete skins motion/reaction which can cause added roughness for ex.; and many other things such as comfort and economy) and coaches."
Dr Morvan who is now working with Speedo towards the 2012 Olympics in London said: “We are now building up toward active drag which accounts for the athlete motion and its interaction with the free surface. This should further validate the suit design as we move to the 2012 Olympics
