Embedded software tech firm Lynx Software Technologies and aerospace semiconductor manufacturer Teledyne e2v have developed a new development platform designed to reduce risk and time needed to certify safety-critical power applications.
The platform, according to the companies, aims to accelerate the path to certifiability for safety critical Power Architecture applications in avionics and other domains that demand high reliability.
The announcement follows the porting of LynxOS-178, a field-hardened and DO-178C certified hard real-time operating system, to the Teledyne e2v Qormino QT1040-4GB Common Computer Platform, a compact custom platform including a Power Architecture based Processor, 4GB of DDR4 memory, and benefitting from DO-254 certification support.
According to the two companies, LynxOS-178 is the first and only commercial RTOS which has been approved by the Federal Aviation Administration (FAA) as a Reusable Software Component (RSC), and acceptable for use in DO-178 design assurance level A systems per the Advisory Circular (AC) 20-148.
Teledyne e2v marketing and business development manager of digital processing solutions, Thimas Guillemain, comments:
"The integration of the market's only commercially available Reusable Software Component RTOS, LynxOS-178, with our DO-254 certification ready Qormino QT1040-4GB Power Architecture based platform is an exciting opportunity for our mutual customers to accelerate their certified system development. Qormino reduces their design cycle time, and enhances their ability to stay in the market with our 15+ year support commitment."
Teledyne e2v's Qormino QT1040-4GB combines NXP QorIQ T1040 Quad Core Power Architecture processor and 4GB of DDR4 memory on a custom substrate which reduces development time, simplifies designs and allows space savings on the printed circuit board (PCB). QT1040-4GB is shipping today to customers, targeted at High Reliability environments up to military temperature Range (-55C to 125C), and is supplied with a DO-254 Data Package.
Lynx Software Technologies vice president of global sales Lee Cresswell adds:
"The LynxOS-178 RSC significantly reduces the risk, effort and cost of certification according to DO-178C. Acting as a 'reusable hardware component' the Teledyne e2v Qormino module similarly speeds and simplifies certification to DO-254. Coupling with our RTOS RSC provides customer benefits in terms of both time-to-market and time-in-market as their software applications evolve, and reinforces Lynx's commitment to working with its partners and customers to fundamentally reduce the cost of developing, certifying and sustaining avionics designs."
The LynxOS-178 RTOS is an open standards hard real-time DO-178B/C level A certified operating system with natively implemented POSIX APIs and FACE compatibility. LynxOS-178 also provides support for ARINC 653 services, ARINC 653 time and space partitioning, and the deployment of applications developed according to ARINC 653 Application Executive (APEX) APIs. LynxOS-178 is designed specifically to fulfil the stringent needs of multithread and multiprocessing applications in safety-critical real-time systems.
LynxOS-178 2.2.4, supporting NXP T series devices, is available today. Certification artifacts for the LynxOS-178 RSC are available today to support certification according to DO-178C up to DAL
A Qormino QT1040-4GB Evaluation & Open Development Platform is available today.
A LynxOS-178 Board support Package (BSP) for the Qormino QT1040-4GB Development Board is immediately available as an early access release
