ARM Introduces Dual-Core Cortex-R5, R7 MPCore

"Processor design company ARM has today unveiled two new updates to its Cortex-R range of processors: the Cortex-R5 MPCore and the Cortex-R7 MPCore. While the Cortex-A processors can be found in mainstream consumer products such as cell phones and tablet devices, the Cortex-R chips are meant for deeply-embedded and system-on-a-chip duties. Notably you can find the last generation Cortex-R4 in hard disk drive controllers, wireless baseband processors, and automotive systems."

Why Graphene Won’t Replace Silicon in Microprocessors

Over the last three years, we've seen a lot of impressive demonstrations of what the material graphene (a single-atom wide sheet of carbon with the atoms spread in an hexagonal mesh) can do. However, according to IBM, graphene does not have an energy gap, which means that graphene transistors can't be "switched on and off", and thus that they are unsuitable for use inside of microprocessors.

Acer Could Exit Netbook Market

"Acer is developing a pair of Intel-based tablets in what could be a wider exit from the entire netbook category, the company's Taiwan sales manager Lu Bing-hsian said on Tuesday. The seven- and 10-inch slates would use quad-core versions of Sandy Bridge-era Core processors but, reportedly, run on Android rather than Windows 7. Rather than serve as complements, they were directly intended to help in "phasing out netbooks," IDG was told."

Move to ARM Chip Cuts XO Laptop Power Use to 2 Watts

"While the availability of power in certain regions of the world cannot be solved by the OLPC, it can improve upon the power use of the XO Laptop. And with v1.75 they have managed to half that power use. The reason this has been made possible is the move to use an ARM rather than an x86 processor. So now rather than drawing 4 watts of power, the XO-1.75 draws 2 watts. The new chip being used is a 1GHz Armada 610 from Marvell." Update : Here are some clarifications regarding the use of ARM chips and Linux at OLPC.

NVIDIA Announces ARM CPU for Desktop, Server, HPC

Just - just hold on a second. This is big: NVIDIA, maker of graphics accelerator chips, has just announced, during its keynote at CES, that it is developing a high-performance ARM-based processor together with ARM, targeted squarely at the desktop, server, and even high-performance computing markets. That Windows on ARM thing? NVIDIA referenced it multiple times! Update: Boom, and we have a press release. "NVIDIA announced today that it plans to build high-performance ARM based CPU cores, designed to support future products ranging from personal computers and servers to workstations and supercomputers. Known under the internal codename 'Project Denver', this initiative features an NVIDIA CPU running the ARM instruction set, which will be fully integrated on the same chip as the NVIDIA GPU."

What Will Power Computing for the Next 10 Years and Beyond?

The CPU industy is working on 16nm chips to debut by around 2013, but how much smaller can it go? According to the smart guys, not much smaller, stating that at 11nm they hit a problem relating to a 'quanting tunneling' phenomena. So what's next? Yes, they can still add core after core, but this might reach a plato by around 2020. AMD's CTO predicts the 'core wars' will subside by 2020 (there seems to be life left in adding cores as Intel demonstrated a few days ago, the feasibility of a 1000 core processor.) A Silicon.com feature discusses some potential technologies that can enhance or supersede silicon.
