Increasing processor efficiency by matching power with demand

By - February 28, 2011 2 Pictures
For decades, chipmakers strove to develop the fastest and most powerful chips possible and damn the amount of electricity needed to power them, but these days raw grunt isn't the only consideration. As more and more devices go mobile and these devices become more and more powerful, chipmakers must also take the energy efficiency into account. Harvard graduate student Wonyoung Kim has developed and demonstrated an on-chip, multi-core voltage regulator (MCVR) that he says could allow the creation of "smarter" smartphones, slimmer laptops and more energy efficient data centers by more closely matching the power supply to the demand of the chip.

Microfluidic chip device identifies bacteria types

By - September 16, 2010 1 Picture
A team of biomedical engineers at Taiwan’s National Cheng Kung University has created a new “on-chip” method to identify bacteria. By creating microchannels between two roughened glass slides containing gold electrodes, the researchers are able to sort and concentrate bacteria. A form of spectroscopy is then applied to identify them, providing a portable device that can be used for tasks like food monitoring and blood-screening. Read More

Scientists create a multitool for working with nanoparticles

By - August 16, 2010 2 Pictures
If you had to sort a bunch of nanoparticles by size, what would you use? A microscope, tweezers, and a very finely-calibrated caliper? Actually, you’d probably use the nanofluidic “multi-tool” created by researchers at the National Institute of Standards and Technology (NIST) in the US. Before you start picturing a teeny-tiny Leatherman, which would admittedly be pretty cool, you should be aware that the NIST device is more like a coin separator, that sorts your nickels, dimes and quarters. In this case, however, they would be nickels, dimes and quarters that are smaller than a bacterium. Read More

What do you get when you cross a CPU with a GPU? AMD’s Fusion family of APUs

By - June 3, 2010 9 Pictures
At Computex 2010 AMD gave the first public demonstration of its Fusion processor that combines the Central Processing Unit (CPU) and Graphics Processing Unit (GPU) on a single chip. The AMD Fusion family of Accelerated Processing Units (APUs) not only adds another acronym to the computer lexicon, but ushers is what AMD says is a significant shift in processor architecture and capabilities.

Scientist infects himself with a computer virus

By - May 27, 2010 1 Picture
A researcher from the UK's University of Reading has warned of possible future infection issues for recipients of medical implants. The cause for concern is not biological, though. Dr. Mark Gasson's disquiet relates to the fact that as implants become more sophisticated, the computerized systems running them could become prone to virus attack. And to prove his point, the good doctor purposely infected a chip implanted in his hand with a virus, which subsequently spread to an external communication system. Read More

Researchers show off tiny piezoelectric energy capture sensor

By - January 7, 2010 1 Picture
Working within the Holst Centre program on Micropower Generation and Storage, researchers have developed a small piezoelectric device capable of harvesting 85 microwatts of electricity from vibrations. Fabricated using MEMS technology, the fully autonomous temperature sensor generates enough power to wirelessly measure and transmit environmental data to a base station every 15 seconds. Read More

A microchip that detects the type and severity of cancer in just half an hour

By - September 29, 2009 2 Pictures
Because the signature biomarkers that indicate the presence of cancer at the cellular level are generally present only at low levels in biological samples, detecting them is a procedure that usually takes days and involves a room filled with computers. Now researchers have used nanomaterials to develop a microchip small enough to fit in a device the size of a mobile phone, and sensitive enough to do the job in 30 minutes. Read More

Intel Core i7 Mobile Processor - fastest ever laptop chips

By - September 24, 2009 1 Picture
Intel says processing power that was reserved for desktop computing can now be conducted on laptops equipped with its new Intel Core i7 Mobile Processor and Intel Core i7 Mobile Processor Extreme Edition. Using its award-winning and super-fast Nehalem microarchitecture, along with the new Intel PM55 Express Chipset, gamers, photographers, digital music mixers, movie-makers, etc, will no longer have to be anchored to a desktop computer to access the processing power they need.
