Reusable software reduces risk for safety certifiable PowerPC development
Partnering to deliver a compact, powerful hardware and software development platform for safety-critical Power Architecture applications, Lynx Software Technologies and Teledyne e2v have announced the LynxOS-178 FAA approved reusable software component has been ported to Teledyne e2v’s DO-254 ready Qormino QT1040-4GB common computer platform.
The embedded software company and the aerospace-qualified manufacturer of advanced semiconductors announced the porting of LynxOS-178, a proven, field-hardened and DO-178C certified hard real-time operating system (RTOS), to the Teledyne e2v Qormino QT1040-4GB compact, custom platform including a Power Architecture-based processor, 4Gbyte of DDR4 memory, and benefitting from DO-254 certification support.
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.
Thomas Guillemain, marketing and business development manager of Digital Processing Solutions at Teledyne e2v described the integration as “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,” he said.
Lee Cresswell, vice president of global sales at Lynx, added: “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 … benefits in terms of both time-to-market and time-in-market as their software applications evolve . . . [to] fundamentally reduce the cost of developing, certifying and sustaining avionics designs.”
Teledyne e2v’s Qormino QT1040-4GB combines NXP QorIQ T1040 Quad Core Power Architecture processor and 4Gbyte of DDR4 memory on a custom substrate which reduces development time, simplifies designs and allows space savings on the PCB. QT1040-4GB is shipping today to customers, targeted at high-reliability environments up to the military temperature range of -55 to +125 degrees C, and is supplied with a DO-254 data package.
The LynxOS-178 RTOS is an open standards hard real-time DO-178B/C level A certified OS with natively implemented POSIX APIs and FACE compatibility. LynxOS-178 also supports ARINC 653 services, ARINC 653 time and space partitioning, and applications developed according to ARINC 653 APplication EXecutive (APEX) APIs. LynxOS-178 is designed specifically to fulfil the stringent needs of multi-thread and multiprocessing applications in safety-critical, real-time systems.
LynxOS-178 2.2.4, supporting NXP T series devices, is available today. Certification artefacts for the LynxOS-178 RSC are available now to support certification according to DO-178C up to DAL A Qormino QT1040-4GB evaluation and open development platform is available today.
A LynxOS-178 board support package (BSP) for the Qormino QT1040-4GB development board is available as an early access release.
