PHOENIX – DDC-I in Phoenix is introducing the Deos DO-178 safety-critical real-time operating system (RTOS) software compatibility with the Mercury Systems ROCK-2 mission computing architecture.

Embedded computing solutions based on the ROCK-2 architecture running Deos RTOS can simplify the flight-safety certification process of mission-critical computers to reduce program risk, while saving cost and time.

Deos is a safety-critical avionics RTOS that hosts flight-critical functions like air data computers, air data inertial reference units, cockpit video, displays, flight instrumentation, flight management systems, and engine management.

Built for safety-critical applications, Deos is a certifiable time- and space-partitioned COTS RTOS created using RTCA DO-178 Level A processes. Its modular embedded computing design and verification evidence provides an easy and low-cost path to DO-178C DAL A certification -- the highest level of safety criticality.

DDC-I's SafeMC technology extends DDC-I's advanced time and space partitioning capabilities to multiple cores, enabling developers of safety-critical systems to get multicore performance without compromising safety-critical task response and guaranteed execution times.

The ROCK-2 architecture features BuiltSAFE technology, bringing a high level of flight-safety assurance to aerospace and defense applications.

BuiltSAFE is an open-systems 3U OpenVPX form factor that is compatible with the Sensor Open Systems Architecture (SOSA). Together, ROCK-2 and BuiltSAFE offer interoperable NXP and multi-core Intel based real-time processing hardware, software, networking, datalink, graphics, and I/O building blocks with supporting flight-safety certification artifacts.

"Deos' time and space partitioning, SafeMC multicore technology, and IOI deterministic data distribution service are a perfect fit for ROCK-2's modular, multi-slot, multi-partitioned hardware architecture," says Greg Rose, vice president of marketing and product management at DDC-I.
