Community First, Commercial Complement – William Mills, Chief Technologist for Open Linux Solutions, Texas Instruments
Open source enables a community of developers to innovate fast and share resources in developing and debugging Linux. However, this model does not meet all the needs of embedded product developers, especially those who want significant structure in their software development, planned development schedules, enhanced development tools, and maintained versions of code releases specific to their particular product releases - not to mention differentiated leverage of the advanced features available with advanced processors. So can you have the best of both worlds? This entails speed and community leverage as well as the innovation of open source environments that brings structure, enhanced tools, code release stability and differentiation of classic embedded. We think you can, so this talk will discuss how to navigate the community and commercial options for Linux on advanced embedded processors. (13 slides)

Real-time vs. real fast: How to choose? – Paul McKenney, Distinguished engineer, IBM
Although "real-time is not real-fast" is a nice sound bite, it does not provide much guidance to developers. This paper will provide the background needed to make a considered design choice between "real time" (getting started as quickly as possible) and "real fast" (getting done quickly once started). In many ways, "real fast" and "real time" are Aesop's tortoise and hare, respectively. But in the real world of real time, sometimes the race goes to the tortoise and sometimes it goes to the hare, depending on the requirements as well as the details of the workload. (47 slides)

Strategies to improve embedded Linux application performance beyond ordinary techniques – Anderson Medeiros, Software Engineer, Motorola and André Oriani, Software Engineer, Motorola
The common recipe for performance improvement is to profile an application, identify the most time-consuming routines, and finally select them for optimization. Sometimes that is not enough. Developers may have to look inside the OS searching for performance improvement opportunities. Or they might need to optimize code inside a third party library they do not have access to. For those cases, other strategies can be used. This presentation reports the experiences of Motorola's Brazilian developers reducing the startup time of an application on Motorola's MOTOMAGX embedded Linux platform. Most of the optimization was performed in the binary loading stage, prior to the execution of the entry point function. This endeavor required use of Linux ABI and Linux Loader going beyond typical bottleneck searching. The presentation will cover prelink, dynamic library loading, tuning of shared objects, and enhancing user experience. A live demo will show the use of prelink and other tools to improve performance of general Linux platforms when libraries are used. (50 slides)

Using Virtual Hardware to Help Embedded Software Development – Ross Dickson, Principal Technology Specialist, Virtutech, Inc.
With a virtual platform, software for a target system is tested on the development host PC instead of on an actual physical target board. This benefits developers. The virtual platform can be made available before physical hardware prototypes, saving time to market. It provides a more convenient software execution environment, speeding up edit-compile-debug cycles. It also provides unique debug abilities such as synchronous breakpoints for an entire system, the ability to non-intrusively inspect the target state, checkpoint save and restore, and reversible execution and debug. It also makes it possible to analyze the performance of code in great detail, in a way not possible on physical hardware. This talk will introduce how virtual platforms work, how they can be built, and show some real-world examples. (35 slides)

Booting Linux on embedded PowerPC systems – Matt Tyrlik
There are two approaches for booting the operating system on a computer system. One requires the OS to have detailed knowledge of the underlying hardware, which requires the OS to contain code specific to each hardware platform implementation. The second approach relies on the firmware to provide the OS with an abstracted view of the hardware, which minimizes the amount of platform dependent code and reduces OS changes required to support new hardware platforms. The Linux community has chosen the second approach for all PowerPC 64-bit and 32-bit Linux board support implementations, based on the Open Firmware device tree concept. Topics covered will include the Open Firmware device tree concept as implemented on PowerPC systems, discussion related to passing the device tree information between the firmware and the OS, the flat device tree implementation and device tree compiler, and work currently carried out by the Power.org consortium to standardize the device tree structure for PowerPC embedded systems and to provide architecture specification for PowerPC embedded systems.

Embedded Mobile Software: Task-Oriented Programming
– Bill Lee, Sr. Manager, Developer Relations
, ACCESS
As Moore's Law plays its role in embedded products by increasing power and reducing package size, it opens the opportunities for a broader audience of developers to develop embedded mobile applications. At the same time, software applications for mobile should take into consideration the resource restrictions of embedded solutions as well as the special task-oriented usage model of mobile devices. The ACCESS Linux Platform (ALP) uses the open-source Hiker middleware framework to enable application developers to create applications that integrate those design and usage patterns. This session will touch on the relevance of these issues and give insight into an application structure for mobile software that can be applied to any mobile platform. (47 slides)
