PHOENIX – Mission-critical software specialist DDC-I in Phoenix and embedded computing designer North Atlantic Industries in Bohemia, N.Y., are teaming to provide safety-critical industry-standard computer software and hardware for avionics applications.

DDC-I and North Atlantic are introducing the North Atlantic 68PPC2 T2080 PowerPC OpenVPX single-board computer with a Deos DO-178C Design Assurance Level A (DAL A) verified FACE-conformant real-time operating system and a DAL A Board Support Package (BSP) from DDC-I.

The BSP provides DO-178C/ED-12C DAL A verification evidence, including high-assurance boot, several Ethernet channels that use the T2080 DPAA, PCI Express, SATA flash storage, I2C, serial real-time clock, watch dog timer, SPI, USB, and GPIO.

This combination of mission-critical embedded computing hardware and software can help accelerate development, deployment, and certification of high-performance safety-critical avionics applications.

The computer hardware and software emphasize modular, scalable, and portable DAL-A verification. Deos uses a DAL-A linking loader to enable operating system binary components and their artifacts to travel separately.

North Atlantic's Configurable Open Systems Architecture (COSA) uses modular, portable components that can be added or removed, and reapplied to other system configurations with maximum reuse of DAL-A safety-critical artifacts.

This can enable avionics designers using Deos and the COSA architecture to reconfigure their I/O systems with minimal effect on hardware, software and DO-178 recertification.

Deos is a safety-critical embedded real-time operating system with cache partitioning, memory pools, and safe scheduling to deliver high CPU use.

Deos combines DO-178C DAL A artifacts with Future Airborne Capability Environment (FACE) technical standard support that encompasses the Safety Base and Safety Extended Profiles for the Operating System Segment (OSS).

The North Atlantic 68PPC2 is a 3U OpenVPX NXP T2080 PowerPC single-board computer that users can configure with as many as two North Atlantic smart I/O and communications modules.
