While such warnings from the market analysts are not to be dismissed, a skeptical attitude in general is recommended by Jack Ganssle in “Hope and horror. ” His conclusion: “The standard deviations are so huge, over such short periods of time, that one is inexorably drawn to the conclusion that their reports are meaningless .”
Design article activity on the site this week has included smarter single battery designs, embedded software test automation, and hardware design project management. My Editor's Top Picks are:
To deal with a problem in software certification known as the “Big Freeze” (where all components and tools are frozen in place once a workable design has been achieved) the authors use the “Big Thaw”: continuous monitoring of all activities affected by a change, to keep all artifacts up to date and to preserve the complete system's certifiability.
Developers can overcome the issues of reliable bug reproduction and communication of the target state using virtual platform checkpoints. By such mechanisms, any bug can be captured, communicated, and reproduced any number of times, in any location.
As video architectures evolve, existing dedicated point-to-point architectures are likely to give way to packetized router technologies that resemble standardized, high-bandwidth Ethernet switches used in carrier and telecommunications applications.
Micrium's Matt Gordon provides an introduction to real-time kernels with a particular focus on what embedded developers of medical devices will need to know to begin writing multi-task applications.
Meeting the challenge is to find automated in-target software testing tools that can be easily integrated into developers' embedded development environments.
Erik Welsh, a security architect in TI's Application Specific Products Organization answers the question “I'm not sure I need to secure my embedded design? If I do, how do I begin and which type of security should I enable?”
Best practices in the development and maintenance of application programming interfaces (APIs) dictate that software interfaces do not change once they have been released, with the exception of adding new entry points. So, it's important to design concise, extensible interfaces that can be adapted to survive in an evolving hardware/software ecosystem.
Use of the Common Weakness and Enumeration (CWE) database allows security quality attributes to be specified for a project, allowing them to be measured and verified before an embedded design is put into service, significantly reducing in-the-field exploitation of latent security vulnerabilities
Virtual hardware platforms can be leveraged to obtain significant project and product planning improvements in terms of development time, time-to-market, and development process risk.
