Mixing Modern Multi-core Processors with Open Architectures

This white paper discusses the development of a next-generation smart avionics display platform, addressing the challenges and requirements associated with integrating modern multi-core processors and open architectures in the aerospace industry. It outlines the increasing demand for enhanced situational awareness and operational efficiency in aircraft, which has led to the adoption of multi-core processors. The paper details the implications of this technology shift on avionics software and hardware safety certification standards, specifically RTCA DO-178C and DO-254. It also highlights the evolving relationships between original equipment manufacturers, system integrators, and component providers, emphasizing the need for modular and open system designs. The paper presents various technical aspects, including the use of ARMv8 processors, hardware virtualization, and advanced GPU acceleration, while documenting the lessons learned from the project and comparing results with previous-generation platforms. Additionally, it discusses the role of software in avionics displays and the development of the Modular Open System Architecture platform (MOSArt) to enhance flexibility and portability in avionics systems.
