Will ARM Get OpenCL Certification?
ARM has submitted its Mali-T604 GPU for OpenCL certification.
ARM’s Mali GPUs have so far shyed away from GPGPU support, however as smartphones and tablets are not expected to see an ever growing number of processor cores the cries for OpenCL support in its GPUs have been growing louder. Now ARM has submitted its Mali-T604 GPU to the Khronos consortium for full profile OpenCL certification.
The Khronos consortium oversees the development of OpenCL and the high-level language is supported by a number of firms including AMD, Nvidia and Intel on their latest GPUs. However until now there hasn’t been an OpenCL certified GPU that is used in smartphones, though firms such as Zii Labs also boast OpenCL support for their chips.
ARM said, “Building on a scalable multicore, multi-pipeline architecture design, the Mali-T600 Series GPU includes a number of advanced features. In particular, native scalar and vector operations for OpenCL’s integer and floating point data types (including 64-bit); support for static and dynamic compilation; hardware accelerated image and sampler data types; fast atomic operations and compliance to IEEE754-2008 precision requirements.

Comments Off on Huawei Investigating Security Flaws
Huawei Technologies said on Thursday it was investigating claims that its routers contained critical vulnerabilities, after security researchers disclosed alleged problems last.
“We are aware of the media reports on security vulnerabilities in some small Huawei routers and are verifying these claims,” Huawei said in an email. The company added it uses “rigorous security strategies and policies” to protect the networks of its customers, while following industry standards and best practices concerning security.
“Huawei has established a robust response system to address product security gaps and vulnerabilities,” the company said. The company is also calling on industry to promptly report all product security risks so that the problems can be addressed and fixed, it said in its email.
The alleged security vulnerabilities were disclosed at the Defcon hackers conference this past Sunday by two security researchers. The vulnerabilities were found in the firmware of Huawei AR18 and AR29 series routers, which once exploited through the flaws, could be taken over via the Internet.
One of the researchers, Felix Lindner the head of security firm Recurity Labs, described the security of the Huawei devices he analyzed as “the worst ever”, and said there were bound to be more security flaws with the products.

AT&T plans to buy NextWave Wireless, a holder of spectrum that could be used for mobile data services, for about $600 million.
NextWave owns licenses for spectrum in both the WCS (Wireless Communications Services) and the AWS (Advanced Wireless Services) band. AT&T said in a press release it plans to use that spectrum to feed “skyrocketing” demand for mobile data, but it will have to wait for an ongoing Federal Communications Commission review before it can take advantage of the WCS band.
The FCC auctioned WCS spectrum in 1997, but it has not been used for mobile data because of rules designed to prevent interference with satellite users in adjacent bands, AT&T said. In June, AT&T and satellite radio company Sirius XM filed a proposal to the FCC for using WCS while protecting the nearby satellite users, but the agency is still reviewing that plan. If it is approved, AT&T hopes to start using the WCS band in about three years.
The NextWave deal is only the latest in a series of moves by big mobile operators to secure more spectrum. AT&T characterized its proposed merger with T-Mobile USA last year, which was opposed by the FCC and other regulators, as first and foremost a deal to acquire spectrum. Verizon Wireless announced a deal earlier this year, which is still under FCC review, to acquire unused wireless licenses from major U.S. cable operators.
ZTE Pushes Past RIM
ZTE became the world’s fifth largest smartphone vendor in the second quarter, it announced today, overtaking Research in Motion (RIM).
That’s according to research firm IDC’s Worldwide Quarterly Mobile Phone Tracker, which shows that thanks to sales of eight million smartphones in the second quarter ZTE has slipped onto the top five list. RIM, which was fourth on the list in May, is now nowhere to be seen, as sales of the firm’s Blackberry handsets continue to falter.
With eight millions smartphones shifted in the second quarter, ZTE’s shipments increased 300 per cent compared to the second quarter last year, helping it snatch a 5.2 per cent share of the worldwide market and making it the fastest growing smartphone maker after Apple. This puts the firm just 0.5 per cent behind Android phone maker HTC and just 1.4 per cent behind Nokia.
Unsurprisingly, rivals Apple and Samsung fill the top two spots, holding on to 16.9 per cent and 32.6 per cent of the smartphone market, respectively.
“ZTE’s great smartphone performance in 2012 in international markets has been a major contributor to our consistent expansion, and is a demonstration of the depth and strength of our R & D,” said ZTE EVP and head of its Terminal Division He Shiyou.
“We have moved into the middle to high-end smartphone market with the recent launch of the ZTE Grand X in countries including China, Turkey and the UK, and we will continue to build our handset capabilities in the middle and high range sectors, while still delivering great lower-end smartphones like the ZTE Kis.”
PC Sales Takes Toll On Seagate
Seagate Technology Plc’s shares tumbled as much as 8 percent on Tuesday, after the hard disk drive (HDD) maker projected first-quarter revenue below estimates on slowing sales of personal computers.
The company has been hit by sluggish economic growth and shaky sales of PCs as consumers shift toward tablets and smartphones.
FBN Securities cut its price target on Seagate’s stock to $32, saying selling prices had started to decline from their peak levels after theThailand floods last year and inventory had started rising.
Seagate’s weak outlook follows an upbeat fiscal 2013 forecast from rival Western Digital Corp, which is banking on strong sales to big businesses.
The company forecast first-quarter sales of about $4 billion, below analysts’ estimates of $4.62 billion, according to Thomson Reuters I/B/E/S.
Microsoft Gives Money To Hackers
Microsoft has given out more than $250,000 in prize money to Black Hat hackers who found ways to protect its software. Redmond’s first Blue Hat prize were unveiled at a hip club at a mobbed party complete with dancers, high-energy DJ, and explosions of shimmering confetti.
The top prize of $200,000 went to doctoral student Vasilis Pappas. Pappas came up with a method to countering “the most popular attack technique” that Redmond is seeing at the moment. This is called Return-Oriented Programming which is a hacker technique that is often used to disable or circumvent a program’s computer security controls. Pappas came up with something called kBouncer which blocks anything that looks like an ROP attack from running.
Microsoft security response center senior director Mike Reavey said that Redmond posed a challenge to the researcher community and asked them to shift their focus from solely identifying and reporting individual vulnerabilities to investing in new lines of defensive research that could mitigate entire classes of attacks.
Artificial Photosynthesis Developed

Comments Off on Artificial Photosynthesis Developed
Panasonic said on Monday it has created a new system for artificial photosynthesis that can remove carbon dioxide from the air almost as well as plants do, as part of the company’s entry into an industry-wide trend toward greener tech.
The company said its system uses nitride semiconductors, which are widely used in LEDs (light-emitting diodes) to convert light to energy, and a metal catalyst to convert carbon dioxide and water to formic acid, which is widely used in dyes, leather production and as a preservative.
Carbon dioxide is a major pollutant and considered to be a main cause of the “greenhouse effect,” which most climate scientists believe causes global warming.
Panasonic has struggled with its traditional electronics business and has made eco-friendly products and practices the key element in its turnaround plan. The company is hoping to leverage its large rechargeable battery and solar businesses, while joining the industry in embracing technologies that are friendlier to the environment. The issue is an important one with customers, as demonstrated by the the outcry earlier this month when Apple was forced to rejoin a green standards program when clients complained about its earlier withdrawal.
Panasonic said the system can convert carbon dioxide and water to formic acid with an efficiency of 0.2 percent in laboratory conditions, which is similar to the conversion rate for green plants. The efficiency refers to the portion of the incoming light energy stored in materials produced during the process.
ARM Profits On The Rise
ARM has reported good second quarter financial results, with profit rising by 23 per cent to $102.97 million.
ARM has been riding high in the public consciousness thanks to firms such as Qualcomm, Texas Instruments and Nvidia pushing its chip architecture into smartphones and tablets. The firm announced it managed to take in $209.78 millio in revenue during the second quarter, a 15 per cent increase from the same period last year, while net income rose even faster by 23 per cent to $102.97 million.
ARM said two billion chips using the firm’s various design models were shipped during the quarter, which represented a nine per cent increase from last year. The firm revealed that its core money making operation, processor royalties, rose by 14 per cent.
Warren East, CEO of ARM said, “ARM’s royalty revenues continued to outperform the overall semiconductor industry as our customers gained market share within existing markets and launched products which are taking ARM technology into new markets.
“This quarter we have seen multiple market leaders announce exciting new products including computers and servers from Dell and Microsoft, and embedded applications from Freescale and Toshiba. In addition, ARM and TSMC announced a partnership to optimise next generation ARM processors and physical IP and TSMC’s FinFET process technology.”
Lenovo Launches The IdeaPad
Although it was introduced six months ago at CES, Lenovo’s new IdeaTab has finally showed up at Lenovo’s site with a pretty decent price around $343.20. The IdeaPad comes with a 10.1-inch screen, Qualcomm’s dual-core Snapdragon S4 CPU, Android 4.0 ICS and optional keyboard dock, it certainly sounds like a good deal.
The specification list for the Ideatab S2110 kicks off with a 10.1-inch IPS 1280×800 display, Qualcomm’s 1.5GHz dual-core Snapdragon S4 CPU, 1GB of RAM and Android 4.0 ICS OS. The rest of the specs include back 5MP and front 1.3MP cameras, 802.11bgn WiFi, Bluetooth 4.0, and a battery capable of up to 9-10 hours of WiFi web browsing, according to Lenovo.
Same as the Asus Transformer line of tablets, Lenovo’s Ideatab S2110 also features an optional keyboard dock that gives you an extra ten hours of battery life and adds two USB ports and a card reader.
Windows Malware Hides In iOS App
Windows malware slipped past Apple’s eye and has been found tucked into software available on the company’s iOS App Store.
Although the malware, labeled a worm by Microsoft and tagged as “Win32/VB.CB” by the company, is harmless against Apple’s iOS and OS X operating systems, it may pose a threat to iTunes customers who download iPhone and iPad apps to their Windows PCs before syncing to their mobile devices.
A user reported Win32/VB.CB to Apple’s support forum around 10:30 a.m. ET Tuesday. The user, identified only as ”deesto,” said that his or her OS X antivirus warned that “Instaquotes-Quotes Cards for Instagram” was infected.
