Storing Files Safely on Portable Devices
The requirements for file storage on portable devices are driven by interoperability and reliability in a battery powered environment. Portable devices typically share data with external systems such as a desktop computer in a standardized format. Power loss or surge while accessing a storage device poses a significant risk of corrupting file system data. This paper will discuss the file system requirements of portable devices along with suggesting strategies for meeting the design requirements.

Power Management for Portable Consumer Electronic Devices
For manufacturers of portable consumer electronic devices, reducing power consumption is a goal with returns that far outweigh the investment. By utilizing Mentor’s Nucleus Power Management facility along with other performance tuning techniques, system developers can help device manufacturers improve time between recharges, reduce overall BOM costs, and qualify their product as a green device.
This paper covers the basics of reactive power management, as well as the more advanced topic of proactive or predictive power management. System integrators and developers well gain a better understanding of these power management techniques and how these techniques can reduce power consumption.
Doing Medical Right with Nucleus
The design and development of electronic devices is no trivial matter - especially when the devices serve the medical industry. As the expense of developing electronic devices continues to rise, engineering teams are turning to commercial off-the-shelf (COTS) software to address the cost issue. The question is, while COTS software is used in arenas such as consumer electronics, mobile phones, etc., can it also be used in the production of safety critical devices? This paper discusses the similarities and illustrates the benefits gained by using the Nucleus OS approach when developing today's medical devices.
Nucleus Platform Solutions
Electronic devices are evolving at a breakneck pace as manufacturers strive to differentiate from the crowd with more features, lower power consumption, and a better user experience. Such enhancements might be great for the end user, but they cause major headaches for the software developer who must deliver ever more sophisticated software on top of ever more complex silicon, and still get products out the door on time and within budget. What's needed is a new kind of development platform which empowers electronic devices: flexible enough to be reused across a wide range of products and scalable enough to exploit the unique capabilities of any target silicon.

Nucleus OS - Accelerating Encryption on the PowerPC 8349E
The focus of this technical paper is on how the Nucleus OS Security Services can be used to exploit the encryption hardware available on the PPC8349E to achieve significant performance increases. This paper is part of the Nucleus OS Security Services reference platform that is also available on this website. The evaluation platform provides a complete system for utilizing and evaluating the performance of the MD4, MD5, SHA-1, SHA-256, DES, 3DES, CAST-128, Blowfish, and AES encryption algorithms using either pure software or hardware acceleration.
Enabling DaVinci Technology with Mentor Software
This white paper discusses the features of Texas Instruments' DaVinci platform and how Mentor Graphics provides a complete solution to support this platform. This solution includes a discussion on the EDGE developer Suite, Nucleus OS, and Inflexion Platform UI. This paper further delves into how the DaVinci platform can be used in different multimedia based devices and provides an example to work through the details.
Emerging Embedded Technology in the Automotive Industry
Exciting times these are! The automotive technology industry is seeing a whole new trend taking shape. Car technology is just in its infancy and already there are many interesting concepts being rolled out from major car manufacturers all over the world. There have been early successes and minor setbacks in this highly competitive industry. This paper will attempt to outline some of the advances that have been made recently, and based upon past trends, will predict the direction this industry is going. In the mind of the author, this direction holds enormous potential for new applications of embedded technology, can bring a wave of new trends and mega-trends in the automobile industry, accounts for many years of sustained fruitful business for car manufacturers and increases value and functionality. It also decreases costs with every coming year for the person who matters the most: the car buyer.
