Prep patents with reverse engineering in mind
Any company that files patents as part of its intellectual property strategy should be actively thinking about the end use of those assets.
Secure by Design: Using a Microkernel RTOS to Build Secure, Fault-Tolerant Systems
When securing an embedded system, a protective barrier facing the external threats is a good start. But security within the system is still required to prevent the damage if an attack breaks through. This technical paper looks at how an RTOS can provide mechanisms to prevent software processes from damaging other processes within the system.
DSPs evolving, but coding/debug needs to catch up or we're in trouble
DSPs are great, but they will only sort themselves out when the language to program and then simulate and debug the code improves, else, we are going to have more glitches as code gets reused and more band aids put around it to do more things.
Virtualization makes better use of open-source OSes and apps
The increased use of software virtualization in embedded systems is allowing additional use of open-source operating systems and applications.
Ten sites with engineering appeal
he Internet's strength--limitless content--can also be its most maddening quality for a user trying to pinpoint information.
ESL: Where are we and where we are going
Electronic System Level (ESL) design is a 21st century phenomenon. Although other disciplines that have used computer-aided-design methods have done system-level design for years, electronic designers have begun to employ this method only recently. From the very beginning of the industrial semiconductor era, now over fifty years old, engineers have paid more attention to structures in silicon than to system architecture. Methods have grown bottom-up, from mylar strips to gates, to registers, to functional blocks. EDA tools have naturally followed the same evolution.
Keeping your priorities straight: Part 3 - Understanding the implications
Priority assignment can have a big impact on the number of context switches a real-time application performs. In this three part series, William Lamie gives you the basics on how to do it right. Part 3: Understanding the implications
Keeping your priorities straight: Part 2 - Operational flow (Two examples)
Priority assignment can have a big impact on the number of context switches a real-time application performs. In this three part series, William Lamie gives you the basics on how to do it right. Part 2: The operational flow of a context switch.
