ARM Showcases Innovation in Mobile Technology at 2009 GSMA Mobile World Congress with ThinkFree Mobile
WHAT: At the 2009 GSMA Mobile World Congress, ARM will offer attendees the opportunity to experience the latest mobile trends and strategies. A series of product demonstrations and Partner activities will provide an opportunity to learn about tomorrow’s mobile technology solutions today. 2008 was an exciting time for ARM with several milestones reached: ARM® Partners shipped 10bn chips into the mobile market, an average of two ARM processors per mobile phone First showing of ARM technology on 32nm HKMG wafer Launch of wide range of innovative devices including the G1 handset and the first Cortex™-A8 processor-powered mobile phones. In addition, ARM CTO, Mike Muller, will present on the topic “Mobile Web2.0 & Open Source”, as part of the Mobilizing Open Source track and ARM is sponsoring the International Mobile Gaming Awards. Product demonstrations at the ARM stand 1C01 in Hall 1 will include: Symbian Symmetric Multiprocessing Demonstration on the ARM Cortex-A9 Processor See the first public demonstration of two new technologies working together that will be key to the future of the mobile industry: The ARM Cortex-A9 MPCore™ multicore processor delivering notebook performance with the power footprint of mobile, and Symbian OS SMP capability. The second-generation MPCore multicore processor enables the sharing of workload among processors, providing more processing performance on-demand with lower power consumption overall. This will enable greater responsiveness to the multiple tasks with which a smartphone has to cope, whilst extending battery life. ARM Netbooks, Hybrids and MIDs....All-Day Mobile Computing ARM and its Partners are redefining Mobile Computing to enable a full web experience, all-day battery life and a diverse range of attractive low-cost consumer products. ARM will be showing a broad selection of ARM Powered® devices based on the ARMv7 architecture, such as the Cortex-A8 processor. With a wide choice of Partner technology, attendees will also be able to learn about the ARM ecosystem built around these devices. This technology is driving battery life, full web experience, and differentiation in devices. On the booth you can see: Cortex-A8 processor vs Intel Atom power comparison Pegatron Netbook running Ubuntu Hybrid Notebook Software for Mobile Computing & Mobile Web 2.0 Notebook Linux distributions, office suites, fast boot technology and Android running on high-performance Cortex-A8/ARMv7A processors are demonstrated here. These software components are important to the emerging trend of Web-orientated Netbooks and Hybrid Notebooks. ARM has a diverse ecosystem that brings Web2.0 to ARM Powered devices in your hands. On the booth you can see: Ubuntu with Firefox 3 Phoenix Technologies™ Hyperspace™ running on Cortex-A8 processor Thinkfree™ office suite with Sun’s Java SE on Qualcomm SnapDragon™-powered Inventec Netbook Alpha release of Ubuntu 9.04 for ARM will be shown running on Cortex-A8 processor-based systems. Ubuntu 9.04 is scheduled for full release in April 2009. ARM Mali™-200 GPU – Bringing Visual Entertainment to Life Advanced user interface software and compelling gaming experience show what is possible with the scalable, power-efficient Mali graphics processors and OpenGL ES 2.0-compliant high-quality driver software, supporting resolutions up to 1080p enabling a rich graphical user-interface on mobile devices, more realistic navigation and gaming. The Mali-200 hardware at the booth will be demonstrating: OpenGL ES 2.0 delivering the next generation of UIs beyond today’s OpenGL ES 1.1 UIs Next generation of mobile gaming capabilities Wide range of new visual effects using programmable shaders Mali GPUs zero cost FSAA allowing smooth rendering of images on the small screen RealView® Development Suite 4.0 with ARM Profiler This demonstration will show how the use of the RealView Development Suite from ARM enables software engineers to get the best out of their ARM technology-based device. With features such as non-intrusive profiling of applications for unlimited duration, developers can quickly and accurately target their optimizations to improve performance and size on applications, firmware and Symbian OS-based systems. With immediate feedback on actual application performance and rapid identification of bottlenecks across a broad range of performance measurements, bringing applications to market is achieved faster and with lower risk with ARM. In addition, ARM CTO, Mike Muller will deliver a presentation examining the increasing role of Open Source in enabling Mobile Web 2.0 centric devices. Mobile Web 2.0 & Open Source will be part of the conference session, “Mobilizing Open Source”, taking place on Wednesday, February 18, 2009 at 14:00-17:30 in Hall 5, Auditorium 2. This presentation discusses how Open Source web components such as WebKit and Javascript JIT engines and now complete platforms are transforming the Smartphone into a Web centric de
A Router may be added to a Deeter Wireless Sensor System in order to significantly increase the radio range and to improve communications reliability. The basic wireless sensor system comprises of a Deeter Base Station and a single remote sensor node (either a Sender or LVCS-RF). The maximum achievable range between these two devices can exceed 1km. However, in many practical environments the signal can be attenuated by obstructions and fading as a result of multiple signal paths caused by reflections. These effects reduce the communications link quality and reduce the achievable range. The router enables you to overcome this by extending the range of the overall wireless system. The Wireless Router should be placed midway between the remote sensor and Base Station. It may be better to place the Router off to one side of the direct line between these two devices when there are obstructions in the direct path. The communication link quality will be improved increasing reliability. Up to four Routers may be used in a single system, with data messages passing in several hops between the remote sensor node and the Base Station. This will enable the system to transmit over an even larger range, multiplying the range four times. If multiple Routers are used then the network builds the best route between the Base Station and remote sensor node when the system is started. If communications are interrupted, perhaps as a result of an obstructing object moving into the signal path then the network rebuilds the routing table after a short delay. The Router must be permanently powered ready to relay messages. Any message sent by the Base Station to a sleeping battery powered remote sensor node will wait at the last Router until the device awakes and polls for data. Wireless communication uses the internationally recognized IEEE 802.15.4 protocol in the 2.4GHz ISM radio band. This allows users to install approved devices without needing to obtain a site licence. The Router is housed in a sturdy ABS enclosure with an external antenna. Power is supplied from a 5Vdc mains wall adapter through a cable gland. An optional extension lead and bracket kit is available for mounting the antenna remotely in an elevated position more favourable to wireless communication.
