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

By Mark Brown | Systems Architect on Jan 28, 2020 2:20:00 PM

_______________

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 at DSEI JAPAN 2019

By Dan Westerberg | Senior Systems Engineer on Nov 18, 2019 2:29:00 PM

_______________

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:

How to Choose a Real-Time Operating System

By Tim Loveless | Principal Solutions Architect on Oct 14, 2019 10:32:00 AM

_______________

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 vehicles on the road, so the range of available cars is obvious. When choosing an RTOS, the middle ground is crowded—dozens of general-purpose RTOSes with broadly similar characteristics compete.  They all have a scheduler, services, libraries, middleware, technical support, and graphical tools. Any one of them could genuinely do a good job and so choosing between them is a mixture of quantitative metrics (like features and price) and qualitative measures (like past-experience, personal-preference, and reputation).

Realizing modern Automotive Software Environments

By Chris Barlow | Technical Product Manager on Oct 9, 2019 2:17:00 PM

_______________

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.

Multi-core cache allocation technology (CAT) demo

By Tim Loveless | Principal Solutions Architect on Oct 3, 2019 2:04:00 PM

_______________

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.

Field Notes: Sept 2019 Face™ TIM

By James Deutch | Principal Field Applications Engineer on Sep 24, 2019 2:24:00 PM

_______________

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.
