Huntsville, AL – January 8, 2026. DDC-I, a leading supplier of software and professional services for mission and safety-critical applications, today announced that it will exhibit its Deos™ DO-178C, multi-core avionics real-time operating system (RTOS) at the Military Aviation & Air Dominance Summit, which will be held January 21-22 at the Jackson Center in Huntsville, AL.
The 8th Annual Summit will convene senior-level experts and decision-makers from across the U.S. military services, DoW, international partners, acquisition authorities, and industry for a joint service discussion on strategies, initiatives, and emerging capabilities critical for enhancing lethality and restoring the warrior ethos in pursuit of total air dominance.
“DDC-I has pioneered the development of safety-critical avionics software and multi-core technology, and has been at the forefront of standardization efforts like DO-178C, FACE® and MOSA,” said Gary Gilliland, vice president of marketing at DDC-I. “Deos offers a readily-certifiable, easy to integrate RTOS platform that delivers best in class multi-core performance, modularity, reuse and interoperability, and has flown for millions of hours aboard commercial air transport, business jet, military aircraft and helicopters. We look forward to sharing our technology with avionics innovators at the Military Aviation & Air Dominance Summit in Huntsville.”
About Deos
Deos is a safety-critical time and space partitioned RTOS that has been developed to DO-178C/ED-12C Design Assurance Level A (DAL A) for avionics applications – the industry benchmark for software process quality. It supports multiple scheduling paradigms (ARINC 653 APEX, Rate Monotonic Scheduling (RMS), POSIX) and is targeted at the Future Airborne Capability Environment (FACE™) Safety Extended and Safety Base Profiles. Its partitioning enables the mix of software with different design assurances on the same processor and provides fault isolation (and application restart) without impacting the operation of other software components. The Deos microkernel architecture provides a building block component structure that isolates reusable software components for robustness and enables system improvements to be fielded much faster.
DDC-I’s 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 developers to address issues specified by AC/AMC 20-193 multi-core objectives that could impact the safety, performance, and integrity of a software airborne system.
