Take better iPhone photos in low light with Cortex Camera

The iPhone 4S' camera does an admirable job in a variety of lighting conditions, particularly when you remember that the device is a phone first, and a camera second. Still, if you find yourself shooting in low-light situations, you probably have noticed that your photos look blurry or grainy. Cortex Camera is a $2.99 app that can reduce this graininess or noise when shooting in low light. Here's how it works:

Instead of taking a single, still photo, Cortex Camera actually captures a short video when you hit the shutter button. Thus, you will need to hold your … Read more

Heads up, Intel: TSMC cranks up ARM chip to 3GHz

Taiwan Semiconductor Manufacturing Company has ripped a page right out of the Intel playbook.

TSMC announced today that a chip rolling off its advanced 28-nanometer manufacturing process was jacked up to 3.1GHz -- unheard of in the annals of ARM-based mobile system reviews.

Intel, of course, is not a stranger to fast frequencies. Its high-performance Core i desktop processors run well more than 3GHz, and even its higher-end mobile parts are rated close to 3GHz.

But that's unfamiliar territory for ARM, which is known more for power efficiency than raw power.

More specifically, the TSMC chip is a … Read more

Samsung announces quad-core chip for Galaxy S phone

Electronics heavyweight Samsung will put quad-core silicon in its next Galaxy smartphone, upping the ante for mobile performance.

The Exynos 4 Quad integrates four processor cores and is built on the company's cutting-edge 32-nanometer manufacturing process. The chip will run at speeds above 1.4GHz, the company said in a statement today.

As a yardstick, the third-generation iPad uses older 45-nanometer Samsung manufacturing tech and its central processing unit is dual-core (though the graphics processing unit is quad-core). And most multi-core smartphones and tablets on the market today are dual-core.

Samsung's new chip -- targeted at both tablets … Read more

Qualcomm S4 chip renders Ice Cream Sandwich 'butter smooth'

Qualcomm's Snapdragon S4 chip is racking up benchmark numbers that make the Samsung Galaxy S II's performance seem so last-year while turning Ice Cream Sandwich into a dreamy experience, said a chip review site.

"Occasionally we'll see performance numbers that just make us laugh at their absurdity," said Anandtech. "[Snapdragon S4's] Linpack performance is no exception. The performance advantage here is insane. The MSM8960 is able to deliver more than twice the performance of any currently shipping SoC (system-on-a-chip)."

And what about that Adreno graphics processing unit? "From a compute standpoint … Read more

Smartphone, tablet demand boosts profits for ARM

ARM can thank the booming smartphone and tablet market for its solid fourth-quarter performance.

With its chips popping up in the iPhone and an array of other mobile devices, the U.K.-based company saw its pretax profit surge 45 percent to 69 million pounds ($108 million), while its sales rose 21 percent to $217 million.

But it's actually the royalties that provided the biggest boost. The company takes home a royalty for every ARM-based product sold along with a license to use its technology, notes the Wall Street Journal (subscription required)

As a result, fourth-quarter royalty sales grew … Read more

Samsung's 2GHz chip to drive new tablet displays

Samsung is readying a 2GHz chip with amped up graphics, offering more evidence of a wave of high-resolution tablets to come.

The Exynos 5250 dual-core chip is based on the latest and greatest Cortex-A15 ARM design. And just in case you're not sure what kind of device the chip is targeted at, Samsung leaves no doubt. The 5250 is "designed specifically for high-end tablets," according to Samsung's press release.

But let's get the nuts and bolts out of the way first. It uses 32-nanometer "high-k metal gate" process technology (translation: smaller chip geometries … Read more

A6 chip to reach iPad 3 later in 2012, says analyst

Apple's latest chip technology won't appear in the next-generation iPad until June 2012 at the earliest, according to a firm that tracks the mobile processor industry.

Getting new processor technology out the door (remember, Apple is also in the chip design business) is a Herculean task for even seasoned chip manufacturers like Intel. It will certainly be no different for Apple, whose next chip, dubbed the "A6," may not make an appearance in the iPad 3 until later in 2012, said The Linley Group, a chip consulting firm.

If Apple keeps to its schedule and launches … Read more

Rumor: iPhone 5 to feature A5 processor, iPad 2 stays with A4

The oft-quoted DigiTimes, a Taiwanese tech industry favorite publication, has revealed that Apple is outsourcing the production of its A5 processor chip, which many expect will be based on the ARM Cortex A9 design and used in the forthcoming iPhone 5, to Taiwan Semiconductor Manufacturing Co.

AppleInsider reports that Apple's A4 chip is currently produced by Samsung Electronics, but the move to Taiwan Semiconductor for production of the A5 chip is because of Samsung's inability to keep up with Apple's supply demands.

This rumor follows many regarding Apple's iPhone lineup, including a larger, 4-inch screen and … Read more

Inside Sony's next-generation PSP

Sony's disclosure of the internals of the Next Generation Portable (NGP) PlayStation at an event in Tokyo today reveals a game engine that might be best described as an Apple iPad on steroids. Lots of steroids.

Like the iPad (and iPhone), Sony will use an ARM processor design. Of course, Sony and Apple aren't the only high-profile device makers using ARM chips. Motorola is using an advanced ARM chip from Nvidia in its Xoom tablet, and RIM's BlackBerry PlayBook tablet will tap a powerful ARM chip from Texas Instruments. Both of those are dual-core ARM designs.

But … Read more

ARM's Cortex gains server features

ARM has released some details of its forthcoming 2.5GHz Cortex A15 processor, at an event in San Francisco on Wednesday.

The chip, previously code-named Eagle, will be built in 32nm and 28nm processes by IBM, GlobalFoundries, and Samsung. The core is superscalar, capable of running multiple instructions through a pipeline, and ARM says that it will perform up to five times faster than the current ARM 9 architecture.

The company said it would be used in "superphones" (high-performance smartphones), home entertainment, small servers, and wireless infrastructure, in one- to eight-core configurations and beyond.
