DDC-I provides DO-178C certifiable software and tools for safety critical avionics. Deos™, from DDC-I, is a time and space partitioned RTOS which has been certified to DO-178 Design Assurance Level A (DAL A) since 1998 and is flying in over 10,000 aircraft. Developed from day one using DAL A plans and procedures, Deos features hard real-time response, industry standard ARINC-653 and FACE 3.1 Safety Extended/Safety Base Profiles, and shared resource partitioning to deliver the highest CPU utilization and performance in the industry. Additionally, Deos’s innovative SafeMC and Cache Partitioning technologies for multicore processors best addresses the FAA CAST-32A objectives for minimizing and bounding multicore interference.

LDRA has partnered with DDC-I to deliver a powerful and efficient solution for developing, verifying, and hosting production code in the safety-critical cockpit environment. The LDRA tool suite together with the Deos™ safety-critical real-time operating system with SafeMC™ multicore technology, and the OpenArbor® Eclipse-based IDE, enables a source code static and dynamic analysis, improves code quality, safety, and security, and reduces testing costs.
