Nvidia and ARM forced to bail out battery makers

Friday, November 11th, 2011

ARM and Nvidia are major mobile players, so it pays to listen when the firms announce new technologies. The latest developments from both serve up an interesting similarity with regards to how these companies are tackling one of the biggest annoyances of the modern smartphone: inefficient batteries.

ARM’s recent announcement, big.LITTLE, pairs one of its high-end Cortex A15 MPCore chips alongside an entry-level Cortex A7, which consumes much less power. It’s designed to seamlessly takes over when a device is tackling low-intensity tasks, so the power-sucking A15 is reserved for intensive games and apps.

Nvidia’s Tegra 3 chipset, meanwhile, uses a near-identical approach: the four cores on the main chip can be turned on and off to tackle everything from basic web browsing to high-end games but, if the phone’s in standby mode or you’re running low-power apps, those four cores will shut down, with processing power provided by a “Companion Core”. It’s based on the same Cortex A9 used by the main Tegra 3 chip but, crucially, it runs at 500MHz instead of 1.4GHz. (more…)

Toshiba Folio 100 tablet review: first look

Thursday, September 2nd, 2010

After traipsing around the semi-completed halls of Berlin’s IFA show, it seems like every manufacturer under the sun has decided to release a tablet. Toshiba is no exception, but its Folio 100 tablet has decided to tread a slightly different path to its rivals. The 10.1in form factor and Android 2.2 OS come as no surprise, but Intel and Qualcomm don’t get a look in – instead Nvidia’s Tegra 2 takes centre stage.

All eyes on Nvidia as GTC kicks off

Wednesday, September 30th, 2009

After last week’s Intel Developer Forum, it’s now Nvidia’s turn. Later on today the company will open its three-day GPU Technology Conference in San Jose – a more formal affair than last year’s flashy “Nvision” expo, but still a high-profile international event, and one which yours truly is lucky enough to be attending.

(The picture, in case you’re wondering, is a strange engine-type affair that’s been set up at the entrance to the delegates’ hotel, apparently to welcome us as we arrive. I guess that’s how they communicate with one another down here in the Valley.) (more…)

Hands on with Nvidia Tegra

Friday, June 19th, 2009

Nvidia’s Tegra was first introduced in June 2008, touted as a “computer on a chip” that would saunter into numerous types of device – most notably MIDs – and beat Intel’s Atom at its own game. It’s been all quiet on the Tegra front since, but we’ve finally had the chance to go hands on with Nvidia’s exciting new technology.

The ARM11 core (which is also used in the Zune, several Nokia phones and the HTC Dream) is the main processor but, for tasks that have specialist demands, several other chips are included: a GPU handles gaming and 3D tasks, an audio unit is optimised for mp3 and radio playback, a 2D graphics chip can handle a camera.

Separate chips tackle video encoding and decoding, with Nvidia promising the ability to encode and decode 720p video simultaneously. The board also houses flash and system memory, which are the larger chips towards the bottom of the PCB.
