Join Wind River, Intel, and EE Times in this web seminar panel discussion to learn more about the technology and business trends that will change the way devices are architected and developed, and how you can prepare for this future with the right multicore and virtualization technologies.

With the recent launch of Android 2.0, learn how using the ARM platform when developing for Android using the Android NDK (Native Development Kit), will help make full use of your CPU and deliver leading edge Android applications. Follow the performance improvements of a simple processing intensive Image application moving from a pure Android version, to native C, optimized assembler and finally to a high performance NEON implementation.

Semiconductor IP leaders Sonics, Inc. and MIPS Technologies team to illustrate the most effective ways to optimize your wireless SoCs for superior performance, power and cost efficiencies, and system flexibility. The presenters will also share the on-chip 'must-haves' essential for high-performance, power-aware wireless designs.

This class uses Micrium's recently released uC/OS-III as a reference, and is presented by the kernel's author, Micrium's Founder, Jean Labrosse, in conjunction with one of the company's software experts, Matt Gordon. The class describes real-time kernels from generic terms to specifics involved with an ARM Cortex-M3 architecture.

This webinar includes a briefing from the Mentor Graphics OS engineering team, who will discuss the implementation of Nucleus OS and Linux on the Marvell Sheeva MV78200 Dual-core Embedded Processor.

In this course we will explore some of the fundamentals of ESL with particular emphasis on one of the most mature areas, namely high-level synthesis of the hardware portions of the system. While this area is maturing, different vendors have chosen different languages as their starting point and we will explore some of the tradeoffs that this makes.

This class covers sensorless vector control formulation for Brushless DC (BLDC) motors and its implementation techniques. The class starts with basic theory in terms of BLDC motor model, vector control principle, Clark & Park transformation, PWM modulation, flux observer, and speed and position estimation. Vector control based on sensor and its normal processing is briefly explained. Then the class focuses on processing for a sensorless vector control that does not use position or speed sensors. Specific implementation of the motor model based flux observer and overall sensorless vector control implementation strategy is described. Also, techniques for measuring currents via conventional sensors and using one-shunt reconstruction are explained. Finally, this class demonstrates the performance of sensorless vector control regarding speed regulation and CPU bandwidth usage.

Handheld mobile devices provide an ever richer range of applications and connectivity which, when combined with their limited computing resources and physical accessibility, implies a unique set of security issues. High-value services must operate alongside low-risk features and even user-downloaded applications. The complex mixture requires a rich OS environment which carries with it its own inherent vulnerabilities. This class outlines a security architecture tailored to provide the assurance required for high-value services while at the same time allowing the freedom needed for user-downloaded applications on the same device. Starting with the hardware components providing tamper-resistant monitoring and debug port protection, the class moves through tamper-evident software load and execution and through to system and user data protection. Finally, the class outlines the integration of these elements with software virtualization technology to provide assurance for high-value services. The virtualization solution runs a strictly contained and hardware access-restricted User OS. Alongside, but fully isolated from the User OS, virtualization allows a Trusted Execution Environment (TEE) to run, in which high-value services may operate out of reach of other features and applications.
