When DO-254/DO-178 safety-certifiable COTS boards and systems must take full advantage of the Deos RTOS

Curtiss-Wright collaborates with DDC-I to ensure our DO-254/DO-178 safety-certifiable COTS boards and embedded computing subsystems take full advantage of the capabilities in the Deos real-time operating system (RTOS). Deos is full featured and certifiable to DO-178C Design Assurance Level A (DO-178C DAL A) and it addresses the issues of high robustness and formal certifiability for avionics and safety-critical applications. With DDC-I and Curtiss-Wright, customers can take advantage of the multi-core processing power of Arm and NXP Power Architecture processors in industry-standard VPX/OpenVPX form factors to get their programs started quickly.


  • DDC-I Deos operating system is tested, validated, and supported on Curtiss-Wright’s
    • VPX3-152 and V3-152 SBCs with NXP Power Architecture T2080 processors
    • VPX3-1703 and V3-1703 SBCs with NXP LS1043A Arm processors
  • Rugged solutions ready for laboratory to deployment applications in the aerospace and defense markets
  • For DO-254/DO-178 safety certifiable avionics applications, Curtiss-Wright’s safety-certifiable COTS graphics, I/O, SBC modules and systems provide the reduced cost and development risk benefits of COTS electronics to designers of safety-certifiable systems. Combining Curtiss-Wright safety-certifiable hardware with DDC-I’s time- and space-partitioned, multi-core enabled DO-178C DAL A RTOS enables system integrators to qualify their safety or mission-critical avionics systems with lower risk, lower development costs and faster deployment.

Enabling Multi-Core Processing in DO-254/178 Safety-Certifiable Avionics

Multi-core processors (MCPs) have become increasingly prevalent in aerospace and defense technology. While MCPs are favored by system designers due to their ability to increase computing power without significantly impacting size, weight, and power (SWaP), the challenge lies in ensuring their reliability for certifiable, safety-critical avionics applications. Read the white paper to learn more about the safety-certifiability challenges MCPs face, as well as practices to assure the safe performance of MCP-based systems.
