DDC-I Inc. is introducing Future Airborne Capability Environment (FACE) 3.0 software conformance for the company's Deos safety-critical DO-178 real-time operating system (RTOS) and OpenArbor development tools running on Arm and x86 processors. 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 the time- and space-partitioned Deos RTOS and SafeMC multi-core technology with RTEMS (Real Time Executive for Multiprocessor Systems), a mature, deterministic, open systems, hard-real-time POSIX executive.
Deos provides ARINC 653 APEX interfaces and multi-core scheduling. A para-virtualized implementation of RTEMS, which runs in a secure Deos partition, provides POSIX interfaces and scheduling.
The integrated platform combines the strengths and pedigree of both ARINC 653 and POSIX RTOSs, providing industry-standard interfaces and feature set for conformance with the FACE Technical Standard Safety Base and Security and Operating System Profiles in a time and space partitioned, hard-real-time, multi-core execution model.
Deos is a safety-critical embedded RTOS with cache partitioning, memory pools, and safe scheduling to deliver high CPU use. First certified to DO-178 DAL A in 1998, Deos provides a FACE Safety Base Profile that features hard real-time response, time and space partitioning, and both ARINC-653 and POSIX interfaces.
