TC-16/51: Adding Bottom Up Interference Analysis for MCPs

_______________ I hadn't heard of "bottom up" avionics certification before I read FAA's TC-16/51. But now, looking back at it, I think the authors from Thales Avionics, including Xavier Jean, PhD, proposed a big change in perspective. In their own... Read More

Lynx & ENSCO Demonstrate Avionics Solutions at DSEI JAPAN 2019

The most formidable challenges of modern avionics development programs are often centered around the safety certification process and the corresponding requirements and costs. Equally as challenging to any large development program are the design... Read More

Do You Need a Real-Time Operating System?

_______________ Do Real-Time Operating Systems (RTOSes) consistently provide the most effective platform for realizing your embedded software system design? Most RTOS vendors seem to think so, frequently citing RTOS benefits while rarely discussing... Read More

Embedded Best Practices at Arm Tech-con

_______________ Lynx participated in this year’s Arm TechCon with a booth in the expo hall, where we demoed Lynx MOSA.ic and its components — LynxSecure®, Buildroot Linux, LynxOS-178®, and Lynx Simple Applications (which are bare-metal apps). It was... Read More

How to Choose a Real-Time Operating System

_______________ Choosing an RTOS is not as simple as choosing a car. We know about cars; we know their strengths and weaknesses and we intuitively understand compromises like performance vs practicality or luxury vs price. We see all kinds of... Read More

Realizing modern Automotive Software Environments

_______________ The complexity of today’s automobiles is increasing with every new model on the market. A modern car can contain hundreds of electronic control units and with connectivity and autonomy becoming commonplace, this is increasing... Read More
