PHOENIX, Ariz. DDC-I, a leading supplier of software and professional services for mission- and safety-critical applications, announced that it has received the Future Airborne Capability Environment (FACE) Conformance Certificate for its Deos DO-178C certifiable real-time operating system (RTOS). The certification covers the FACE Technical Standard, Edition 3.0 Safety Base, and Security Profiles for the Operating System Segment (OSS).

The Deos RTOS Platform for FACE Technical Standard 3.0 combines Deos RTOS and SafeMC multicore technology with Real Time Executive for Multiprocessor Systems (RTEMS). Deos provides ARINC 653 APEX interfaces and multicore scheduling. A para-virtualized implementation of RTEMS, which runs in a secure Deos partition, provides POSIX interfaces and scheduling.

Deos is an embedded RTOS that employs patented slack scheduling, memory pools, and cache partitioning to deliver high CPU utilization. Deos is intended to provide a FACE Safety Base Profile that 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 and employs a bound multiprocessing (BMP) extension of the symmetric multiprocessing architecture (SMP), safe scheduling, and cache partitioning.
