1 Engagement Model for Differentiation
Differentiated Products OEM/ODM requirements OEM Partners capture Connecting OEM/ODM to software solutions providers Software Partners Enable software and services vendors Ensure robust support of Semiconductor Partners key applications and capabilities Organization and rally the Open Source Community Open Source community Direct Open Source Common Foundation Contributions
2 Innovating with Open Source Software ARM contributions into open source upstream projects result in performance optimizations across the eco-system Example: ARM has optimized JIT code generation for JavaScript
ARM Optimal JIT Code Key Contributions to One project positively work Generation 2.75X speedup* effects 6 key web technologies
ActionScript JavaScript Virtual Machine Virtual Machine

3 Linux Across the ARM Roadmap ARM Cortex “Low-Power Leadership” Contributing CPU support to Linux kernel Osprey for Cortex-A profiles x1-4 1.6GHz TSMC 40G… Cortex-A9 uClinux for Cortex-R & Cortex-A8 Cortex-M Profiles Validated with ARM x1-4 RealView reference Cortex-R4F Cortex-A5 boards Cortex-R4 Includes support for both ARM & Thumb-2 builds Performance, Functionality Performance, http://www.arm.com/linux SC300 Cortex-M3 http://www.linux-arm.org/git Cortex-M1 Cortex-M0 miniSwift Gate-level netlist 2006 2007 2008 2009 2010
4 Supporting Two Development Models Growing demand for native as well as cross target development Embedded Platforms Open Platforms MIDs, PDA, etc. Netbooks, Nettops, Servers, etc Resource constrained targets … Relatively closed products Native code development cycle Limited storage High-spec platform Build and test process Memory, MHz is relatively complex Easy to reconfigure and expand Cross-development model Access to disk storage Build on PC/x86, test on target platform or simulator
5 ARM Linux Internet Software Platform
Leverages Nokia Maemo™ project Debian Linux as foundation GNOME components and Mozilla web browser
Reference platform to validate integration of software components Support for ARMv6 and ARMv7 Facilitate common development across ARM reference platforms
Provide builds to facilitate access and engagement with respective communities and projects Includes patches not yet mainlined Maintained code base and regular snapshots

8 JavaScript Acceleration 2009 was the year that JavaScript performance accelerated 4 Key Open Source Projects to accelerate JavaScript “TraceMonkey” – Mozilla Foundation “Tamarin”- Adobe “Squirrel Fish (Extreme)”- WebKit “V-8”- Google All accelerate JavaScript by compiling it to native code (JIT) Some yield up to 5X+ performance improvement Example: Factorial is faster than non-optimized C Multiple JavaScript engines to fit the need All Open Source Projects: benefit from each other!
9 Mozilla Firefox and Fennec Browsers Targets Smartbooks, Smartphones, DTV’s… ARM created enhanced “Tamarin” nano JIT code generator ARM created Cairo graphics optimizations using NEON ARM is working with Mozilla to add OpenGLES 2.0 Firefox 3.5 up to 2x faster* than Firefox 3.0 7x JavaScript improvement between Firefox 3.5. and 3.0 Uses ARM optimized JIT code generation Release schedule parity with Intel Firefox 3.6 Dec 2009 Fennec 1.0 scheduled for Nov 2009 Performance parity with Intel
