Safety-critical RTOS goes for RSC
certification
LynuxWorks claims it will achieve FAA Reusable Software Component (RSC) certification for its LynxOS-178 real-time operating system (RTOS), an industry first.
LynuxWorks claims it will achieve FAA Reusable Software Component (RSC) certification for its LynxOS-178 real-time operating system (RTOS), an industry first With RSC certification, developers can significantly decrease time and cost of FAA DO-178 safety certification by reusing the artefacts for the operating system and related libraries

RTOS helps avionics projects get off the ground
The latest version of the LynxOS-178 RTOS adds support for the ARINC-653 APEX interface to meet the most stringent safety and reliability standards for military and commercial avionics systems.
Package puts IA-32 platform to safety-critical use
A new board support package provides a complete, certifiable solution for mil/aero developers seeking to leverage the IA-32 platform.
As a result, developers can concentrate on the certification of the applications software and the hardware specific board support package (BSP) to dramatically reduce costs and time required for approval.
Software reuse is quickly becoming a critical aspect in addressing the cost and quality of software systems.
The goal of software reuse is to leverage software data from previous development efforts to reduce time, cost, and risks of redevelopment efforts.

With RSC certification for LynxOS-178, software reuse becomes a reality for safety critical embedded systems for avionics systems.
RSC certification for LynuxWorks' LynxOS-178 safety-critical RTOS provides embedded developers with a number of benefits, including: higher productivity - RSC provides improved productivity by reducing time of software code development; increased quality - developers can gain improved system performance and reliability because reusable parts have been proven in other designs; quicker time to market - using proven components enables embedded software designers to reduce product schedule risks for quicker time-to-market; and better utilisation of resources - software reuse enables software developers to focus on new software development rather the having to recertify software components, which will help reduce training time and costs.
"Software reuse will fundamentally change the future of embedded software development", said Dr Inder Singh, CEO and Chairman of LynuxWorks.
"Reusable software offers developers tremendous benefits by controlling and reducing software cost and reducing schedule risk, while at the same time improving quality of their designs".
"The impact of RSC certification for LynxOS-178 will be significant for developers of aviation products, for example, as a means to reduce the costs and schedules for new projects".
"RSC certification for LynxOS-178 will provide high payback, allowing developers to leverage software and artefacts that have been certified previously and be confident that they will meet the standards widely accepted and adopted in the commercial avionics industry".
The military and aerospace industry mandates rigorous technical and process requirements for safety-critical computing.
In the USA, these are expressed in the Radio Technical Commission for Aeronautics (RTCA) DO-178B standard that imposes requirements on the development and verification of airborne avionics systems.
The targeted DO-178B certification level is either A - catastrophic; B - hazardous-severe; C - major; D - minor; or E - no effect.
Until the formidable specifications of this standard are met, safety-critical computing systems literally never get off the ground.
LynxOS-178 is a commercial off-the-shelf (COTS) operating system that fully satisfies the objectives of the DO-178B level A specification.
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, with full Posix conformance, LynxOS-178 enables developers to take advantage of the time-to-market and investment-protection benefits of open standards-based development.
The powerful formula of Posix conformance with DO-178B certification will ensure application portability, software reuse and interoperability between embedded systems, as well as meet the most stringent requirements for real-time safety-critical applications.
RSC certification for LynuxWorks' LynxOS-178 safety-critical RTOS is expected by the summer of 2005.
In addition to the RSC certification and the LynxOS-178 kernel, the offering will include a complete artefacts package for the kernel and user library, DO-178B required documentation, code coverage test suites and analysis for 100% modified condition/decision coverage of the kernel and libraries, a full suite of standards-based development tools, and support.
