Light-based 'Metatronics' chip melts minds, not copper
Engineers at the University of Pennsylvania have flipped the switch on a new type of computer circuit. Unlike conventional silicon, the new chip uses light -- not electricity -- to perform its logic. By creating an array of nano-rods, light-flow can be treated like voltage and current. These rods can then be configured to emulate electrical components such as resistors, inductors and capacitors. The benefits of the so-called "metatronic" system would be smaller, faster and more efficient computer chips, which is clearly a welcome prospect. Another curious property the team discovered, is what it calls "stereo-circuitry." Effectively one set of nano-rods can act as two different circuits, depending on the plane of the field. This means your CPU could become a GPU just by changing the signal. We can't speak for the light itself, but our minds are certainly bent.
Julius Blank, chip-making pioneer and Fairchild co-founder, dies at 86
Somber news coming out of Palo Alto today, where Julius Blank, the man who helped found the groundbreaking chipmaker Fairchild Semiconductor Corporation, has passed away at the age of 86. The Manhattan-born Blank (pictured third from left, above) began his engineering career in 1952, when he joined AT&T's Western Electric plant in New Jersey. As a member of the engineering group at the plant, Blank helped create phone technology that allowed users to dial long-distance numbers without going through an operator. It was also at Western Electric where he met fellow engineer Eugene Kleiner. In 1956, Blank and Kleiner left AT&T to work at the lab of Nobel Prize-winning physicist William B. Shockley, but departed just one year later (amid to start Fairchild, alongside a group of six other computer scientists that included future Intel Corporation founders Robert Noyce and Gordon Moore. At their new labs, Blank and his peers developed an inexpensive method for manufacturing silicon chips, earning them $1.5 million in capital from a single investor. As the only two with any manufacturing experience, Blank and Kleiner were charged with bringing the dream to fruition -- a task that required them to build the chips from scratch, beginning with the machinery for growing silicon crystals. They succeeded, of course, and in 1969, Blank left Fairchild to start Xicor, a tech firm that Intersil would later buy for $529 million, in 2004. But his legacy will forever be linked to those early days at Fairchild, where, as Blank described in a 2008 interview, he and his colleagues were able to experience the unique thrill of "building something from nothing." Julius Blank is survived by his two sons, Jeffrey and David, and two grandsons. [Photo courtesy of Joan Seidel / AP 1999]
Researchers show off scalable architecture for quantum computing, expand our minds
Okay, so we might be chasing the flying unicorn of modern technology here -- and, no, we're not talking about the white iPhone 4 -- but as you've probably noticed, our hunger for a quantum computer is basically insatiable. Lucky for us, some folks who actually know something about producing qubits are similarly persistent -- a team of researchers recently presented a scalable quantum chip at a meeting of the American Physical Society in good old Texas. The 6 x 6-cm processor sports four qubits, the basic units of quantum computing, and its creators say it has the potential to be scaled up to support 10 of the things within the year. So what does that mean for our quest for the ultimate super computer? Well, it means we're closer than we used to be... and the dream lives on.
Researchers tout self-repairing multi-core processors
The race for ever-tinier computer chips is on, and barring physical limitations, doesn't seem to be slowing anytime soon -- but with chips, as with humans, the smaller they get, the more fragile they become. A team of researchers called CRISP (Cutting edge Reconfigurable ICs for Stream Processing) is working to create a self-repairing multi-core processor that would allow on-chip components to keep on shrinking, while combating concerns over accelerated degradation. Basically, the team's conceptualized a chip that allows for 100 percent functionality, even with faulty components. With multiple cores sharing tasks, and a run-time resource manager doling out those tasks, the chip can continue to degrade without ever compromising its intended functions -- a process CRISP calls graceful degradation. Once one core fails, the on-chip manager assigns its task to another core, continuing on in this fashion for the complete lifetime of the chip. Of course the technology is still in its infancy, but if CRISP's chips comes to fruition, we could see virtually indestructible processors that make 14nm look bulky by comparison.
