Smartphone chips reach 1GHz

The push towards multimedia, HSDPA and increased reliance on raw computational power may be encapsulated by the iPhone but every smartphone manufacturer is facing the same challenges. And today’s 600MHz powerplants are unlikely to be good enough for tomorrow’s smartphones.
Samsung this week announced a new 1GHz ARM processor, co-developed with US chip design firm Intrinsity, from the same family as the 600MHz Samsung which which powers Apple’s iPhone 3GS. (Although it’s worth noting that this is in fact an 800MHz chip that’s been wound back to 600MHz in order to reduce heat and extend battery life).
Codenamed ‘Hummingbird’, the new chip is said to be compatible with the Samsung S5PC100 processor used in the iPhone 3GS as well as using the same Cortex A8 engine (and ARM v7 architecture).
In addition to clocking at 1GHz, the Hummingbird has been designed on a 45 nanometer manufacturing process – the same scale as used in the latest crop of Intel chips – which also increases power efficiency, leading to longer battery life for devices.
Samsung isn’t the first to produce a 1GHz ARM chip – that medal went to Qualcomm, which already supplies a 1GHz processor for a Toshiba smartphone. Competitor Texas Instruments has also announced that its future series of multi-core OMAP chips will hit 1GHz.
However, even if Samsung’s 1GHz superchip does find its way into the iPhone of 2010, this could be a last blast for the Korean colossus.
Apple is now working on its own processors, based on the company’s acquisition of chip design firm P.A. Semi last year, with recent reports that the team has been split into two groups – one dedicated to an ARM processor for the iPhone, while the other beavers away on an even more capable chip for the long-rumoured Apple media pad tablet thingie.

Google said Sept. 1 Gmail users made more than 10 million calls through its new Call Phones from Gmail feature since it launched a week ago. Launched Aug. 25, Call Phones from Gmail lets users place calls to contacts directly from Gmail. Calls placed from Gmail in the United States and Canada are free and start at 2 cents per minute outside those countries. The tool, which requires Google's voice and video plug-in, lets users click a Call Phone link. This opens a window with a dialer keypad. Users may... |
Google could be ready to turn Gmail into a communications hub by adding the ability to make phone calls from the Google Chat interface. CNET has learned that Google is testing a Web-based service within Gmail that will allow users to place phone calls from their in-boxes. It's launched from the Google Chat window on the lower left-hand side of a Gmail page and allows users to place and receive calls from within their contacts through a user interface that strongly resembles the one used in Google Voice.... |
Whether Google is liable for damages for secretly intercepting data on open WiFi routers across the United States is to be aired out in a Silicon Valley federal court. Eight proposed class-actions from across the country that seek unspecified monetary damages from Google were consolidated this week and transferred to US District Judge James Ware in San Jose, California. Another five cases are likely to join. The lawsuits allege Google violated federal and state privacy laws in collecting fragments of data... |
While LTE starts rolling out from major U.S. carriers in 2011, the WiMAX Forum is hoping to have the so-called WiMAX 2 standard up and ready to go by the start of 2012. Declan Byrne, the marketing director for the WiMAX Forum industry group, says the WiMAX 2 standard, formally known as 802.16m, will be finalized by the Institute of Electrical and Electronics Engineers (IEEE) this November, with an eye toward certifying devices based on the standard throughout 2011. From there, he expects ISPs to start... |
Despite signing up its 500 millionth member last month, the average amount of time spent on Facebook by a Briton has decreased from 30 minutes in December 2009, to 27.36 minutes during June and July 2010. The figures, collated by web-analytics firm Hitwise, show that Facebook is still the second most visited site in the UK, after Google, and that it accounts for one in every six web pages accessed in Britain. However, Robin Goad, Hitwises research director, believes that the figures show that Facebook is... |

Kaspersky Lab, a leading developer of secure content management solutions, announces that the first malicious program classified as a Trojan-SMS has been detected for smartphones running on Google's Android operating system. Named Trojan-SMS.AndroidOS.FakePlayer.a, it has already infected a number of mobile devices. The new malicious program penetrates smartphones running Android in the guise of a harmless media player application. Users are prompted to install a file of just over 13 KB with the standard... |
A reporter at the BBC has created a smartphone application which spies on the owner of the device, in an attempt to prove how straightforward it is to create malicious software for mobiles. Reporter Mark Ward designed a simple noughts and crosses game using a popular smartphone application toolkit. However, the crude game was a cover for a piece of malware, which hid under the hood gathering contacts, copying text messages, logging the phones location and sending it to a specially set up email address.... |
Mobile satellite company Inmarsat has announced more details of a plan to expand its mobile broadband network delivered by satellite. In a statement this week, the company said it had agreed to purchase three 702HP Ka-band satellites from Boeing. The new satellites will be used to create the Inmarsat-5 constellation of satellites, which the company says will provide a worldwide high-speed mobile broadband service called Global Xpress. The new service is expected to be up and running by 2014 and will provide... |
