Recently, at Arizona State University's Biodesign Institute, N.J. Tao and collaborators have found a way to make a key electronic component on a phenomenally tiny scale. Their single-molecule diode is described in this week's online edition of Nature Chemistry.
In the electronics world, diodes are a versatile and ubiquitous component. Appearing in many shapes and sizes, they are used in an endless array of devices and are essential ingredients for the semiconductor industry. Making components including diodes smaller, cheaper, faster and more efficient has been the holy grail of an exploding electronics field, now probing the nanoscale realm.
Smaller size means cheaper cost and better performance for electronic devices. The first generation computer CPU used a few thousand transistors, Tao says noting the steep advance of silicon technology. "Now even simple, cheap computers use millions of transistors on a single chip."

Intel brought its mainstream desktop CPU lineup into the Nehalem era today with the launch of the Core i7 860 and 870, and the Core i5 850. Also launched today is the P55 chipset, which implements a new system architecture that represents a significant break with Intel's past.
The launch of Core i5/i7 and the P55 represent a major step forward for Intel's desktop line, and they bring Nehalem's performance dominance of AMD's offerings onto the mainstream desktop. Intel is now well-positioned against both NVIDIA and AMD/ATI, since the former will soon be squeezed out of the high-volume Intel IGP market entirely (when the GPU goes on-die) and the latter is increasingly forced back into the bargain niche that it had so successfully escaped with the launch of the K8.

Intel will focus on its next generation of smaller and faster chips at a conference next month as it prepares to ship new chips for systems in 2010.
Intel plans to shed more light on the Westmere architecture at the Intel Developer Forum (IDF), which will be held Sept. 22-24 in San Francisco. The company is expected to talk about the architecture behind its future chips for servers, laptops and desktops.
Chips based on Westmere will be made using the advanced 32-nanometer process and should deliver performance and power benefits over existing Intel chips made using the 45-nm process. Initial chips will integrate a CPU and graphics processor in a single package, which could improve graphics performance while drawing less power.

Been itching to get your hands on a personal supercomputer, as NVIDIA's ad wizards put it? The company has just announced that its CUDA-based Tesla C1060 GPU is now available in Dell's Precision R5400, T5500 and T7500 workstations. And just to put things into perspective, NVIDIA points out that a Dell workstation rockin' a single Tesla C1060 has enough going on under the hood to power the control system for the European Extremely Large Telescope project ("the world's largest," apparently).
According to one of the developers, Jeff Meisel at National Instruments, a workstation "equipped with a single Tesla C1060 can achieve near real-time control of the mirror simulation and controller, which before wouldn't be possible in a single machine without the computational density offered by GPUs."

A new, extremely energy-efficient processor chip that provides breakthrough speeds for a variety of computing tasks has been designed by a group at UC Davis. The chip, dubbed AsAP, is ultra-small, fully reprogrammable and highly configurable, so it can be widely adapted to a number of applications.
The chip is designed for digital signal processing. While not the principal kind of processor chip used in desktop computers, digital signal processing chips are found in a myriad of everyday and specialized devices such as cell phones, MP3 music players, video equipment, anti-lock brakes and ultrasound and MRI medical imaging machines.
Maximum clock speed for the 167-processor AsAP is 1.2 gigahertz (GHz), but at slower speeds its energy efficiency soars. Twelve chips working together could perform more than half-a-trillion operations per second (.52 Tera-ops/sec) while using less power than a 7-watt light bulb.

Conventional magnetic storage devices used in consumer electronics, like computer hard drives, MP3 players, and other metallic based products, have separate data storage and execution units. At least part of the delay (or slowness) generated by current products is due to the relatively long way data has to go - being retrieved from the storage, passed to the central processing unit (CPU) for processing and execution, and back again to the storage unit. These back and forth transfers, can dramatically hinder the general performance of the system.
However, the new technology developed by NIST in collaboration with the Korea University and the University of Notre Dame, have proven that thin magnetic layers of semiconductor material could demonstrate antiferromagnetic coupling, where one layer spontaneously lines up its magnetic pole in the opposite direction to the next magnetic layer.

Intel's next-generation Nehalem processor lineup is so powerful that it simply destroys previous CPU benchmarks. An early look at the company's new chips shows they have the potential to drive current data center-class performance onto the desktop.
The Test Center has reviewed evaluation units of the chip giant's latest processors and motherboards over the past several weeks. Early results show nearly historic levels of improvement over previous generations of processors.
Intel, Santa Clara, Calif., made the evaluation units available to reviewers ahead of the platform's official launch, which is expected to happen later this month. ("Nehalem" is actually the former code-name of the platform, which includes its new Core i7 CPUs and X58 motherboards.)
Considered by some to have the most significant new architectural changes since the Pentium Pro, the microarchitecture will include future variants for server and mobile applications.
