2nd Generation IMA development platform for avionic system integrators

Lynx Software Technologies, a specialist in open, mixed criticality and MILS system development, has announced the LynxSecure Safety Bundle for Intel multi-core processors.

The LynxSecure Safety Bundle is an open system architecture solution that unlocks the potential of multi-core to deliver 2nd generation IMA. The LynxSecure Safety Bundle (LSB) integrates the complete range of system development services for platform suppliers to build, deploy and sustain their IMA platform. It enables system integrators to leverage modern multi-core hardware to significantly reduce SWaP (size weight and power) by consolidating multiple Line Replaceable Units (LRUs) onto a single platform. Importantly, it enables an open development capability in which any bare metal, Linux or other RTOS or OS-based system module or application can reside in a single multi-core time and space partitioned system safely and securely. It thus provides system integrators with maximum flexibility to create competitive supply chains that don’t impose the unnecessary cost burden of safe system integration when that functionality is not required.

This solution securely integrates four key capabilities: LynxSecure, a truly secure-by-design separation kernel hypervisor; LynxOS-178, to run safety critical application workloads; a fully supported version of Embedded Linux based on the Buildroot technology for non-critical application workloads; and Luminosity, an Eclipse based Integrated Development Environment. This includes the ability to develop fully separated ‘bare-metal’, OS independent system functions or secure applications using developer tools of choice, thereby meeting the demands for high assurance module development in an open systems development framework.

LynxOS-178 is the only commercial RTOS which has been approved by the Federal Aviation Administration (FAA) as a Reusable Software Component (RSC). Up to 80% of the OS certification costs that developers would normally have to bear to achieve DO-178B/C is removed, even as they move to the latest generation of Intel multi-core processors. LynxSecure assured separation means that only software in the LynxOS-178 partition needs to go through certification even though it resides on the same processor as non-critical applications with no safety requirements. The LynxOS-178 RTOS has been certified to Design Assurance Level (DAL) A, and provides native POSIX API’s, ARINC 653 services, and FACE compatibility.

"In recent years, the avionics industry has taken great strides towards open architectures with the adoption of standards and APIs such as ARINC, POSIX and FACE, and Lynx has fully supported these efforts," said Lee Cresswell, Vice President of Sales, Lynx. "However, vendor lock-in remains a persistent challenge, with system integrators, platform suppliers, module suppliers and application suppliers all facing limitations in terms of operating system environments and toolchains. The LynxSecure Safety Bundle eliminates these vendor lock-in’s and enables the supply chain to develop more cost-effective and performant solutions than would have been possible using proprietary technology."

“Our 2nd generation IMA development platform facilitates rapid technology insertion and modular system component refreshes, enabling suppliers to deliver and monetize system upgrades well into the future, while reusing existing code and rehosting legacy applications in the IMA environment" added John Blevins, Director of Products, Lynx. “The LynxSecure Safety Bundle further demonstrates Lynx’s commitment to working in partnership with its customers to fundamentally reduce the cost of developing, certifying and sustaining avionics designs on complex multi-core architectures.”

Gladys West - Pioneer of GPS
GPS and GNSS positioning technology is such an integral part of our lives today that we rarely stop to think about where it all came from. When we do, we usually picture men in white shirts and dark glasses hunched over calculators and slide rules. In fact, one of the early pioneers behind GPS and GNSS technology was Gladys West - a black woman.
