Embedded computing companies offer safety-critical avionics that meet MOSA and FACE open-systems standards

May 23, 2023
Multicore design and development tools combine open-systems single-board computers, FACE-aligned operating system software, and software framework.

PHOENIX – DDC-I in Phoenix is working together with North Atlantic Industries (NAI) in Bohemia, N.Y., and Real-Time Innovations (RTI) in Sunnyvale, Calif., to offer a MOSA-aligned SWaP-optimized design system for avionics that seek to adhere to the Future Airborne Capability Environment (FACE) open-systems standards.

The multicore design and development tools combine NAI's PowerPC and ARM-based Configurable Open Systems Architecture (COSA) single-board computers and multifunction I/O with DDC-I's Deos' FACE Technical Standard, Edition 3.1-aligned Operating System Segment (OSS) software and RTI's Connext software connectivity framework.

DDC-I, NAI, and RTI share an approach to building safety-critical avionics that align to the Modular Open Systems Approach (MOSA) open-systems design guidelines, and that emphasizes modular, scalable, portable DO-178C DAL A certification evidence.

Deos uses a DAL A linking loader that enables OS binary components and their artifacts to travel separately.

NAI's COSA uses modular, portable components that can be added, removed, and reapplied to other system configurations with maximum reuse of DAL-A artifacts.

RTI Connext TSS employs an open modular framework with DAL A evidence that provides real-time messaging and information sharing for seamless, safety-critical communications, data exchange and interoperability between FACE applications and Deos.

Deos is a safety-critical embedded software real-time operating system (RTOS) that employs cache partitioning, memory pools, and safe scheduling to deliver high CPU utilization on multi-core processors.

SafeMC technology extends Deos' advanced capabilities to multiple cores, enabling developers of safety-critical systems to achieve multi-core performance without compromising safety critical task response and guaranteed execution time.

Connext TSS is a modular certified conformant FACE Transport Services Segment (TSS) software connectivity framework designed to meet the requirements of critical airborne systems requiring low latency, high reliability, scalability, security and commercial DO-178C DAL A certification evidence.

NAI's 68ARM2 VPX single-board computers and NIU3E multifunction I/O processing system feature dual Xilinx Zynq UltraScale+ quad-core ARM Cortex-A53 MPCore processors.
