3/20/2006 - Today’s avionics systems integrators and developers are continually charged to do more with less while at the same time meet demanding cost and time schedules. Software reuse is an important aspect of controlling these software costs as well as improving time-to-market and quality of software systems, especially where the system needs to go through a rigorous certification process. Until today, however, no safety-critical embedded operating system (OS) had received reusable software component (RSC) acceptance by the Federal Aviation Administration (FAA).
LynuxWorks becomes the first and only embedded operating system vendor to receive an Advisory Circular AC 20-148 acceptance letter from the FAA. With RSC approval of the LynuxWorksTM LynxOS-178® real-time operating system (RTOS), embedded systems integrators and developers can consider the operating system portion of the safety-critical software code and supporting DO-178B artefacts for reuse in other system designs with other software components without the need for full recertification. As a result, integrators and developers can significantly reduce the time and cost of achieving FAA certification and further reduce the risk involved in redevelopment efforts across multiple safety-critical systems.
"The time consuming and expensive certification process for safety critical software has been a challenge for developers of such systems," said Dr. Inder Singh, CEO of LynuxWorks. "The LynxOS-178 RSC will lead to a dramatic reduction in the cost and schedule risks associated with such projects. This is very consistent with LynuxWorks’ focus on software reuse through our conformance with open standards and our RTOS and Linux dual product strategy."
A Standards-Based Approach for Reuse
LynuxWorks’ RSC acceptance represents the first standards-based approach for software reuse in airborne systems and equipment to allow system integrators and embedded developers to reuse their existing software. LynxOS-178 addresses system developers’ need to meet FAA certification by providing a time, space and resource partitioned commercial off-the-shelf (COTS) operating system that fully satisfies the objectives of the DO-178B, level A and the ARINC 653 standard as well as full conformance with the IEEE POSIX Standard. Currently, any time a systems integrator or developer wants to integrate components of any other RTOS or any previously certified DO-178B software in multiple hardware, each new hardware/software configuration or system must be recertified. In other words, integrators and developers cannot take full advantage of the software’s existing certification across other multiple platforms, but instead must go through the entire certification process for each new system they build. The RSC acceptance letter from the FAA for LynxOS-178 can be used to support virtually any FAA Technical Standard Order.
"In addition to avionics flight systems, safety-critical software is in embedded military application environments such as weapons systems," said Stephen Balacco, Embedded Systems Market Analyst at Venture Development Corporation. "Today, software drives cost and schedules of embedded system designs. As a result, developers have a need to leverage software reuse from previous development efforts wherever possible and no longer develop software from scratch for each embedded project. RSC has the potential to streamline the software certification process in meeting safety-critical requirements with a reusable component that has been proven in other designs and helps developers reduce design complexity and time-to-market."
"With the industry’s first RSC time and space partitioned RTOS, and by following the guidance of AC 20-148, LynuxWorks raises the bar in delivering the lowest risk solution for Integrated Modular Avionics (IMA) developers," said Joe Wlad, Director of Product Management and FAA DER for LynuxWorks. "Our LynxOS-178 certification artefacts provide IMA developers with guidance on how to build and certify IMA applications more easily. We set out to address a critical customer pain point in helping systems engineers get their future, innovative safety-critical avionics systems to market faster and at lower cost. No other embedded OS vendor can make claim to decreasing the time required for software development and overall costs of avionics equipment that LynuxWorks is now providing in the market today."
About LynxOS-178 RTOS
LynxOS-178 is a commercial off-the-shelf (COTS) time and space partitioned operating system that fully satisfies the objectives of the DO-178B level A specification and meets requirements for Integrated Modular Avionics developers. LynxOS-178 delivers the security and real-time responsiveness needed for safety-critical systems and provides a low-risk path to DO-178B certification for developers to meet the technical requirements in the production of software for airborne systems. In addition, LynxOS-178 provides full POSIX conformance, enabling developers to take advantage of the time-to-market and investment-protection benefits of open standards-based development. The powerful formula of DO-178B certification and POSIX conformance allows developers to meet the most stringent requirements for real-time safety-critical applications while at the same time ensure application portability, software reuse and interoperability between embedded systems.
Availability and Pricing
RSC certification for LynuxWorks’ LynxOS-178 safety-critical RTOS is available immediately at no additional charge. The RSC acceptance applies to a family of PowerPC® microprocessors. LynxOS-178 is approved to support multiple IMA applications at different levels of DO-178B criticality. In addition to the RSC certification and the LynxOS-178 kernel, the offering will include a complete artefacts package for the kernel—including software, requirements documentation, design documentation, requirements coverage, test sweeps, verification procedures and test results—and user library with a full suite of standards-based development tools and support.
