Integration of Software-Defined Radios for Avionics into a Multi-Core IMA Architecture

This paper describes research to integrate various software-defined radio-based communications, navigation, and surveillance systems into a system-on-chip platform. The platform is powered by a multi-core processor and operates on a real-time operating system designed with robust time and space partitioning capabilities, to ensure deterministic performance, fault isolation and secure multi-partition execution (in parallel) within a single hardware environment. As part of the validation process, a case study was conducted with an analysis of results from both laboratory tests and real-world flight tests. These evaluations aim to showcase the feasibility and stability of the proposed design while highlighting significant improvements in the performance and integration of the hardware and software systems and ensuring reliability and robustness in practical aviation scenarios.
