DDC-I Highlights DO-178C, DAL A Multi-core RTOS at 17th Annual Flight Software Workshop

San Antonio, Texas – May 6, 2024.  DDC-I, a leading supplier of software and professional services for mission- and safety-critical applications, today announced that it will exhibit at the 17th Annual Flight Software Workshop. The event, hosted at the Southwest Research Institute, in conjunction with the Jet Propulsion Laboratory, the Johns Hopkins University Applied Physics Laboratory, the Aerospace Corporation, and the NASA Goddard Space Flight Center, runs from May 6-9 in San Antonio Texas.

“Deos has flown for millions of hours aboard commercial air transport, business jet, military aircraft and helicopters,” said Greg Rose, vice president of marketing at DDC-I. “We look forward to demonstrating our world class, safety-critical platform to the aviation and space community at the Flight Software Workshop in San Antonio this year.”

The last several years have witnessed significant advances in next-generation flight system architectures for space, including multi-core, soft-core, FPGAs, space computers, operating systems, flight software and machine learning. This year’s Flight Software Workshop will feature a range of in-depth technical presentations addressing the latest in-flight system technology, including:

  • Resiliency, safety, and security
  • Artificial intelligence, machine learning, and onboard data processing
  • Space networking
  • Onboard data storage and representation
  • Flight software architectures, frameworks, and software buses
  • Software enabled mission concepts
  • Digital twin, config management, and software enabled emulation
  • DevOps, continuous integration, and automated testing
  • FSW, embedded processor, and FPGA interactions
  • Flight Operating Systems
  • New languages (bring your non-C work)

DDC-I will showcase its Deos safety-critical real-time operating system (RTOS), which utilizes the latest DO-178C Design Assurance Level A (DAL A) multi-core verified baseline. First certified to DO-178 DAL A in 1998, Deos combines DO-178C DAL A artifacts with FACE® Technical Standard support that encompasses the Safety Base and Safety Extended Profiles for the Operating System Segment (OSS). The Safety Base Profile features hard real-time response, time, and space partitioning, and both ARINC-653 and POSIX interfaces.

SafeMC technology extends Deos’ advanced capabilities to multiple cores, enabling developers of safety-critical systems to achieve best in class multi-core performance without compromising safety-critical task response and guaranteed execution time. SafeMC employs a bound multiprocessing (BMP) extension of the symmetric multiprocessing architecture (SMP), safe scheduling, and cache partitioning to minimize cross-core contention and interference patterns that affect the performance, safety criticality and certifiability of multi-core systems. These features enable avionics systems developers to address issues that could impact the safety, performance and integrity of a software airborne system executing on Multi-Core Processors (MCP), as specified by the FAA Advisory Circular AC 20-193.
