Lynx Software Technologies

Lynx Software Technologies, Inc. (formerly LynuxWorks)^[1] is a San Jose, California software company founded in 1988.^[2] Lynx specializes in secure virtualization and open, reliable, certifiable real-time operating systems (RTOSes). Originally known as Lynx Real-Time Systems, the company changed its name to LynuxWorks in 2000 after acquiring, and merging with, ISDCorp (Integrated Software & Devices Corporation), an embedded systems company with a strong Linux background. In May 2014, the company changed its name to Lynx Software Technologies.

Over 30 years of processor evolution, Lynx has crafted and adapted platform architectures for builders of safety- and security-critical software systems. Lynx embraced open standards from its inception, with its original RTOS, LynxOS, featuring a UNIX-like user model and standard POSIX interfaces to embedded developers. LynxOS-178 is developed and certified to the distinguished FAA DO-178C DAL A safety standard and received the first and only FAA Reusable Software Component certificate for an RTOS. It supports ARINC API and FACE standards.

Lynx has created technology that has been deployed in thousands of designs and millions of products made by leading communications, industrial, transportation, avionics, aerospace/defense and consumer electronics companies. In 1989, LynxOS, the company's flagship RTOS, was selected for use in the NASA/IBM Space Station Freedom project.^[3] Lynx Software Technologies operating systems are also used in medical, industrial and communications systems around the world.^[4]

In early 2020, Lynx announced that the TR3 modernization program for the joint strike fighter had adopted Lynx’s LYNX MOSA.ic software development framework. The F-35 Lightning II Program (also known as the Joint Strike Fighter Program) is the US Department of Defense's focal point for defining affordable next generation strike aircraft weapon systems It is intended to replace a wide range of existing fighter, strike, and ground attack aircraft for the United States, the United Kingdom, Italy, Canada, Australia, the Netherlands, and their allies. After a competition between the Boeing X-32 and the Lockheed Martin X-35, a final design was chosen based on the X-35. This is the F-35 Lightning II, which will replace various tactical aircraft.

The company’s technology is also used in medical, industrial and communications systems around the world by companies like Airbus, Bosch, Denso, General Dynamics, Lockheed Martin, Raytheon, Rohde and Schwartz and Toyota.^[2]

Operating system evolution and history[]

LynxOS is the company's real-time operating system. It is UNIX-compatible and POSIX-compliant. It features predictable worst-case response time, preemptive scheduling, real-time priorities, ROMable kernel, and memory locking. LynxOS 7.0 is marketed as a "military grade", general purpose multi-core hard real-time operating system, and is intended for developers to embed security features during the design process, rather than adding security features after development. LynxOS and LynxOS-178 have been deployed in millions of safety-critical applications worldwide, including multiple military and aerospace systems.

In 2003, the company introduced the LynxOS-178 real-time operating system, a specialized version of LynxOS geared toward avionics applications that require certification to industry standards such as DO-178B. LynxOS-178 is a commercial off-the-shelf (COTS) RTOS that fully satisfies the objectives of the DO-178B level A specification and meets requirements for Integrated Modular Avionics (IMA) developers. LynxOS-178 is a native POSIX, hard real-time partitioning operating system developed and certified to FAA DO-178B/C DAL A safety standards. It is the only Commercial-off-the-Shelf (COTS) OS to be awarded a Reusable Software Component (RSC) certificate from the FAA for re-usability in DO-178B/C certification projects. LynxOS-178 is the primary host for real-time POSIX and FACE applications within the LYNX MOSA.ic development and integration framework. LynxOS-178 satisfies the PSE 53/54 profiles for both dedicated and multi-purpose real-time as well as FACE applications.

The LynxSecure Hypervisor ("bare metal," type 1) and separation kernel was released in 2005. Within the LYNX MOSA.ic development framework, it acts as a programmable processor partitioning system leveraging hardware virtualization capabilities of modern multi-core processors to isolate computing resources.

In February 2019, Lynx announced LYNX MOSA.ic (pronounced “mosaic”). LYNX MOSA.ic is a software development framework for rapidly building security- and safety-critical software systems out of independent application modules. Designed to deliver on the vision of the Modular Open Systems Approach (MOSA),its focus is to enable developers to collapse existing development cycles to create, certify, and deploy robust, secure platforms for manned and unmanned autonomous systems.

Lynx Software Technologies' patents on LynxOS technology include patent #5,469,571, "Operating System Architecture using Multiple Priority Light Weight kernel Task-based Interrupt Handling," November 21, 1995, and patent #5,594,903, "Operating System architecture with reserved memory space resident program code identified in file system name space," January 14, 1997.^[5]
