MIT's 110-core Execution Migration CPU chip moves instructions to the data

By - October 29, 2013 4 Pictures
A 110-core CPU chip has been developed by computer scientists at the Massachusetts Institute of Technology. The chip is based on a new architecture in which instead of bringing data across the chip to the core that happens to want it, you move the program to the core where the data is stored. In practice, this new architecture reduces the amount of on-chip data exchange tenfold, along with the heat and infrastructure demanded by conventional chip architecture. Read More

Undetectable hardware Trojans could compromise cryptography

By - October 2, 2013 1 Picture
Researchers have shown that it is possible to compromise the functioning of a cryptographic chip without changing its physical layout. Based on altering the distribution of dopants in a few components on the chip during fabrication, this method represents a big challenge for cyber-security as it is nearly impossible to detect with any currently practical detection scheme.

Stanford scientists build first carbon nanotube computer

By - September 26, 2013 3 Pictures
In a technological tour de force, researchers at Stanford University have constructed a one-bit, one-instruction programmable computer on a chip using carbon nanotube-based electronics for all logic elements. Containing 178 carbon nanotube field-effect transistors, the computer is only able to carry out only one instruction, called SUBNEG. However, SUBNEG is Turing-complete, allowing the computer to run, albeit with an extraordinary level of inefficiency, any program, given enough memory, time, and programming ingenuity. Read More

Apple inching further away from Samsung, cuddling up with TSMC for mobile processors

By - June 28, 2013 1 Picture
The relationship between Apple and Samsung is, well, complicated. They're like two bitter exes who work together, or maybe live in the same building. If circumstances permitted, they'd never see each other again. But, try as they may, they just can't get each other out of their lives. Can you say awkward? Well, that relationship is about to take one step closer to complete severance, as Apple is reportedly partially switching to TSMC for the coming year's iOS processors. Read More

Intel targets Ultrabook "2-in-1s" with 4th-gen Intel Core processors

By - June 4, 2013 3 Pictures
Intel is apparently convinced that the future of computing is mobile. Having announced its new Atom Silvermont architecture last month, the chipmaker has introduced its 4th-generation Intel Core processors (code named Haswell), with much of the focus on the power savings that will benefit the battery life of mobile devices. Designed with a new generation of Ultrabooks in mind, Intel says its new processors will provide up to nine hours of battery life with up to two times the graphics capability of previous generations.

D-Wave quantum computer matches the tenth ranked supercomputer for speed

By - May 13, 2013 4 Pictures
There have been years of controversy about whether the superconducting quantum annealing computers manufactured by D-Wave are a) quantum computers; and b) fast enough for a) to matter. Now a test of the 512-qubit Vesuvius chip establishes at least that computing based on quantum annealing is, in the words of a computer science professor at Amherst College, "in some cases, really, really fast."
