DDC-I published a whitepaper titled Safety-Critical Software Integration and Reuse in Avionics.

DDC-I provides DO-178C certifiable software and tools for safety critical avionics. Deos™ is a time and space partitioned RTOS, which has been certified to DO-178 Design Assurance Level A (DAL A) since 1998. Developed from day one using DAL A plans and procedures, Deos features hard real-time response, superior multicore technology, industry standard ARINC653 and FACE Safety Base APIs, and shared resource partitioning to deliver the highest CPU utilization and performance possible in the industry. Additionally, Deos’ innovative SafeMC technology for multicore processors is unmatched, delivering maximum safety-critical performance across multiple cores. Some key advantages of Deos are: • DO-178 Certification Artifact Reuse Through Software Modularity (leveraging certification credit from prior certifications) • Industry Leading SafeMC™ Technology for Safety Critical Systems on Multicore Processors • Time & Space Partitioning (allows mixed levels of criticality running on the same device) • Extensive Certification Pedigree (Certified to DAL A Since 1998) • Patented Slack Scheduling Technology (allows for full processor utilization) • Scalable from Simple LRUs to Complex IMA Systems • ARINC-653, Priority Preemptive, and/or Rate Monotonic Scheduling Available • Industry Standard Application Programming Interfaces (API’s) ARINC-653 & POSIX
