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 words, here's their proposal to add "bottom up" analysis to aircraft safety certifications on Multi-Core Processors (MCP):

Lynx & ENSCO Demonstrate Avionics Solutions @ 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 and implementation phases where the software application comes to life as it is realized on the target system environment. These phases can be compromised by

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 great to see people walk down the hallways and stop in the aisle to examine the Automotive demo and Industrial demo.
The concepts behind the demos apply across multiple industries and use cases; we simply chose to highlight these concepts in the context of these two markets for the purpose of putting together the demos. For more information on the Automotive demo, you can read Chris Barlow's blog post. Below you can see a close-up of the architectural graphic shown on the notebook’s screen:

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 dramatically as we enter the 2020s. Many of these systems up until a few years ago have safely run on microcontrollers on an unsecured vehicle network, and this has been fine; the networks were ‘air-gapped’ from the rest of the world, and the risk of a malicious attacker causing any kind of danger to a car’s occupants by directly plugging in a new device was as likely as someone cutting the brake lines. The automotive industry on the whole were happy with this risk.

Field Notes: Sept 2019 Face™ TIM
Last week I was able to spend several days at the Open Group Future Airborne Capability Environment (FACE™) Technical Interchange Meeting (TIM) and consortium meetings. For those who are not familiar with either the Open Group or FACE™, the Open Group is a global consortium of hundreds of tool vendors, systems integrators, academics, researchers, and consultants aimed at developing open, vendor-neutral technology standards and certifications for various industries, including Defense & Aerospace.

Multi-core cache allocation technology (CAT) demo
This week saw LYNX’s cache partitioning feature for Lynx MOSA.ic™ demonstrated for the first time at the Collins Aerospace Embedded Computing Conference in Cedar Rapids, Iowa. Cache partitioning is a new feature of Lynx MOSA.ic™ released in September 2019 and based on Intel’s Cache Allocation Technology (CAT) CPU hardware feature.
