BOOTH # 1
Wales, UK –October 24, 2025. DDC-I, a leading supplier of software and professional services for mission- and safety-critical applications, today announced that it will showcase its safety-critical DO-178C Deos™ real-time operating system and development tools at the High Integrity Software Conference (HISC), which will be held at the International Convention Center in Wales, UK on November 13. DDC-I’s Spotlight Talk, given by Laurent Meilleur, Vice President of Business Development, will focus on the use of modularity to enhance reusability and compliance.
The need for trustworthy software – software that does exactly what it is intended to do – is well established in sectors such as defense, aerospace, and transportation. But the increased use of software in more domains, including embedded, connected, consumer and infrastructure systems, means that similar approaches are needed across a broader range of industries. In addition, there are disruptive technological influences, which mean that traditional approaches to verification and assurance in the established industries will no longer remain applicable or sufficient.
The mission of the High Integrity Software Conference (HISC) is to bring software engineering practitioners together to share their challenges, best practices, and experiences. The conference program features high-quality content from experts in industry and academia, who will present innovative techniques and methods that software engineers can apply across industry sectors.
“Deos was built from the ground up with a modular architecture and standard interfaces that emphasize portability, scalability and reuse, enabling designers to reconfigure their systems with minimal impact on hardware, software and DO-178 recertification,” said Gary Gilliland, Vice President of Marketing at DDC-I. “We look forward to sharing our best-in-class, safety-critical, multi-core RTOS technology with software professionals and program managers at HISC.”
Deos™ is a safety-critical embedded real-time operating system (RTOS) that employs patented cache partitioning, memory pools, and safe scheduling to deliver higher CPU utilization than any other certifiable safety-critical COTS RTOS on multi-core processors. First certified to DO-178 DAL A in 1998, Deos provides FACE® Conformant OSS Safety Base and Safety Extended Profiles that feature hard real-time response, time, and space partitioning, with support for Rate Monotonic, 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 bounded 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 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.
