TI offers rare demo of Windows 8 Explorer on newest ARM chip

LAS VEGAS--Texas Instruments is offering one of the most revealing demos of Windows 8 on ARM yet at CES.

That's not saying a lot, though, as demos of Microsoft's next operating system on ARM processors have been extremely restrictive, if nonexistent to date in public (Nvidia's untouchable, relatively static CES demo is behind closed glass). But TI pushed the boundaries a bit in a demo for CNET at CES.

The demo tapped TI's freshly minted OMAP4470 ARM processor, according to Bill Crean, an OMAP product marketing manager.

Needless to say, I was not permitted to take … Read more

Next-gen iPhone, iPad could deliver 20 times the graphics power

Owners of upcoming iPhone and iPads could enjoy a boost in graphics power 20 times greater than that offered by current models, according to enthusiast site AppleInsider.

Such a leap in power would come courtesy of new graphics processing units developed by U.K.-based Imagination Technologies, which builds the GPUs for Apple's mobile products.

Announced at CES on Tuesday, Imagination's new PowerVR Series6 GPU core chip family is touted as providing 20 times or more of the performance of the current generation.

As a result, "it enables Imagination's partners to deliver amazing user experiences in … Read more

TI whips out latest ARM chip for Windows 8 tablet

LAS VEGAS--Texas Instruments is showing its latest and greatest ARM processor inside a Windows 8 tablet at CES this week.

TI's OMAP4470, the latest version of its dual-core chip now inside Android tablets, will be shown running on a pre-release version of a Windows 8 tablet, the chipmaker said today.

"The OMAP4470 processor's...powerful multitasking capabilities prove the ideal match for Windows 8 key features including a fast & fluid touch-first user interface," TI said in a statement.

TI ARM chips are being used today in high-profile Android tablets such Motorola's XyBoard and Toshiba's ultra-skinny Excite X10. The 4470 is a performance upgrade of the 4460.

"The company calls it the OMAP 4470, but it is more than just a faster speed grade of the OMAP 4460; the new design includes significant graphics and memory improvements as well," mobile chip analyst Linley Gwennap wrote in a blog last year. … Read more

How small can a high-end speaker be?

PSB Speakers has always been one of my favorite brands. The company gets it, and has a knack for making bona-fide high-end speakers with real-world prices. Even by PSB's high standards the Imagine mini is a standout design.

With a name like mini, you'd expect something small, and at just over 9 inches high, it's nice and compact. The mini's curvaceous cabinet is a five-layer construction of 1/8 inch thick medium-density fiberboard sheets laminated together with a special microwave activated adhesive. The top and bottom panels are also curved to enhance cabinet rigidity and minimize internal standing waves. The mini's molded, rubberized base houses all-metal connectors that accept bare wire ends or wires terminated with spades or pins. The mini is an 8 ohm design. … Read more

Despite legal battle, Apple keeps Samsung inside iPhone

Despite a globe-spanning, bruising legal battle with Samsung, Apple has little choice but to keep getting key parts for its iPhone from the electronics maker, according to sources and a news report.

Those key parts include the iPhone 5's expected main processor, the A5, as well as system memory and flash memory--components that together make up the electronic core.

Sources who track the chip industry say that Apple must stick with Samsung for the time being. Some rumors had claimed that Apple would switch to Taiwan Semiconductor Manufacturing Company (TSMC) for a so-called "shrink" (smaller version) of the A5 for the iPhone 5.

That's simply not doable, sources tell CNET. TSMC has not perfected the advanced manufacturing processes needed to make an A5 for the iPhone and, maybe more importantly, it's prohibitively difficult to jump to a different manufacturer for the same chip design. … Read more

U.S. grad students create app to diagnose malaria

It isn't every day that the second-place winner of a competition is as interesting, if not more so, than the first-place winner. But at the national level of Microsoft's 9th annual Imagine Cup, competition is tight, and the team that took second in the software design category Tuesday deserves attention.

Called Team LifeLens, the students from universities across the country developed an app that uses a Samsung Focus running on Windows 7 to photograph blood samples and diagnose malaria. And they've only been working on it since November 2010.

Computer engineering grad student Tristan Gibeau of the University of Central Florida remembers the day he got the algorithm right to get the cell detector running. "I was ecstatic," he says. "I was running around, just so excited."

According to the World Health Organization, almost 800,000 people die from malaria every year, with 90 percent of the deaths in Sub-Saharan Africa. The beauty of the LifeLens app is that it doesn't require Internet access--just the phone, slide, and app. They're also building a case to hold it all.

Gibeau says the lens "is the last part of the puzzle," and that his team lost to first-place winners Team Note-Taker from Arizona State University because it's still buggy on Windows 7. They're currently working with UC Davis and the actual Windows phone team to get it running smoothly. (The prototype used version 6.5.)

The first-place team, by the way, developed Note-Taker, a camera and touch-screen tablet PC allowing users to simultaneously view live video and take typed or handwritten notes on a split-screen interface.

Inside the iPad 2: Chip brings 50% browsing boost

Wondering what makes that iPad 2 you just got tick and how much faster it is than the original iPad? Anandtech, iFixit, iosnoops, and UBM TechInsights have provided some answers.

Processor performance: Let's address this first--for obvious reasons. Apple has already been very public about the dual-core 1GHz A5 processor--a step up from the single-core chip in the original iPad--and the chip's "up to 9X faster" graphics" (Apple's ad copy).

And the verdict from an independent review? "CPU [Central Processing Unit] performance...we found to be a healthy 50 percent faster than the … Read more

Report: iPad 2 to use fast graphics chip

The iPad 2 will sport powerful, new graphics hardware, along with a higher-resolution display, according to a report.

That graphics chip would be Imagination's SGX543, according to Apple Insider.

If this rumor is on the money, it is, indeed, a potent graphics technology. Imagination describes the POWERVR SGX543MP as allowing "up to 16 cores...in a high-performance, multiprocessor graphics solution without performance or silicon area compromises." This graphics tech would be used in conjunction with a dual-core ARM processor, as CNET previously reported.

And Apple's next-gen iPhone 5 would also feature this chip design--the so-called Apple … Read more

Radiologists rally behind imaging app OsiriX

Just over a year ago, the open-source Mac image viewer OsiriX released its widely hailed medical imaging software for the iPhone. The software was created by a group of radiologists who also proved to be sophisticated programmers, and was hailed by a wider net of radiologists as an app with serious promise.

More recently, scientists from Johns Hopkins University rallied formally behind the app when they presented the results of a study conducted at the University of Virginia in Charlottesville of patients suspected of having acute appendicitis. Reviewing nothing more than computed tomography (CT) scans over an encrypted wireless network using an iPhone 3G with the OsiriX app, researchers were able to diagnose acute appendicitis correctly in 99 percent of the scans of 25 patients, with one false negative.

"This new technology can expedite diagnosis and, therefore, treatment," says Asim Choudhri, a neuroradiologist at JHU who led the study. "We knew that recent advances in handheld device technology allowed viewing of medical imaging, but it [was] unproven whether viewing on a small screen allows a reader to reliably and reproducibly obtain information."

The findings of this study, which Choudhri tells me was funded internally at the UVA Department of Radiology (and yes, his allegiance is clear--he owns an iPhone and in fact supplied it for the study) are encouraging not only for possible appendicitis cases, but a wide range of illnesses such as aneurism and stroke that require fast diagnosis.… Read more
