Best Real-Time Operating System (RTOS) Vendors (2020)

By James Deutch | Principal Field Applications Engineer on May 8, 2020 2:16:17 PM

 _______________

Lynx Software Technologies has built and supported real-time operating systems (RTOSes) since 1988. We have witnessed hardware and embedded software technologies evolve and have supported our customers through the design, development, integration, certification, deployment, and support of software systems across mission-critical applications in avionics, industrial, automotive, medical, and other markets. We talk with many different companies across these markets every year. Over time, we have learned that— depending on the type of system being built—our technologies and products may not always provide the best fit. And that’s OK.

We want you to choose Lynx products because they make the most sense for your project and understanding your options is critical to that process.

It is not uncommon for companies to ask us, "If we were to not use your products, who would you recommend?" Therefore,  with our customers in mind—and with a sincere respect to the companies listed below—here is a list of who we regard as our most solid competitors in the safety-critical embedded systems space, in alphabetical order.

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):

Embedded Best Practices at Arm Tech-con

By James Deutch | Principal Field Applications Engineer on Oct 17, 2019 2:13:00 PM

_______________

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 demos.

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

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.
