ARM Profiler for Symbian OS empowers developers to deliver high performance and reduced power consumption for Symbian OS-based mobile phones

LONDON, United Kingdom - 21 October 2008 - ARM [(LSE: ARM); (Nasdaq: ARMH)] and Symbian Limited today announced at the Symbian Smartphone Show in London, ARM® Profiler for Symbian OS™. As part of the recently-launched RealView® Development Suite 4.0 Professional, the ARM Profiler enables developers of mobile phone applications running on Symbian OS to add enhanced features and reduce power consumption.

Developers can quickly and accurately target their optimisations with immediate feedback on actual application performance and with the rapid identification of bottlenecks across a broad range of performance measurements, bringing their applications to market faster and with lower risk.

"Consumers expect mobile phone applications to deliver advanced features, with the best possible performance and minimal power consumption," said Mike Whittingham, Vice President Ecosystem Development, Symbian. "Developers of complex mobile applications have come to expect the level of power management and performance optimisation found within Symbian OS. The new ARM Profiler provides an analysis environment that enables developers to maximise the performance and power efficiency of their applications, on ARM technology-based mobile phones."

The industry-leading capabilities of the ARM Profiler for Symbian OS build upon ARM's trusted profiling technology which enables non-intrusive, long duration application profiling on hardware or system models; code coverage information, even when source code is unavailable; and the ability to profile fully optimised software. New benefits for developers using the ARM Profiler include:

    * The ability to profile applications running on Symbian OS
    * Profile-driven compilation for automatic code optimisation, based on runtime performance
    * Instruction trace replay for a deeper understanding of application performance

Many profiling tools require code annotation or system instrumentation, which do not provide an accurate representation of application performance or allow profiling capabilities only for very short durations due to buffer limitations. ARM Profiler surpasses these limitations with the ability to analyse fully optimised images, analyse for unlimited durations using the streaming trace feature in RealView Trace 2 and profile the instructions executing on the real time system models from ARM. In addition, with the capacity to analyse the applications running on Symbian OS, engineers can now obtain deeper insight into how applications are affected by system resources and shared libraries for a better understanding of how applications perform as part of a complex system.

"Symbian and ARM have once again collaborated to deliver the very best power and performance advantages for customers using Symbian's industry-leading mobile operating system," said John Cornish, vice president and general manager, System Design Division, ARM. "The innovative features of the ARM Profiler build upon ARM's established technology to provide unparalleled trace and optimisation capabilities, significantly streamlining the development process for next-generation mobile applications running on Symbian OS."
