Flight Test Performances of SDR Avionics on RFSOC 4x2 Running with Certifiable RTOS Environment

The aerospace industry is maximising the performance of avionics systems and at the same time reducing their size, weight, power consumption, and cost (SWaP-C). This is due to the evolution of technologies such as integrated modular avionics (IMA), which allows multiple functions to be performed by a single computing unit. A significant standard for this scheme is ARINC 653, which allows multiple applications to execute in a secure and trustworthy fashion within the stringent constraints of DO-178C-compliant aviation environments. The focus to which the research intends to provide contributions is the interconnectivity of software-defined avionics modules (SDAMs) in a single integrated platform. Such SDAMs could include in-strument landing systems (ILSs), distance-measuring equipment (DME), an automatic dependent surveillance broadcast (ADS-B), and a transponder (XPDR), which are consolidated in one RFSoC 4x2 system. The heart of this system relies on PikeOS, a certified real-time operating system (RTOS) that fulfils some principles of DO-178C and ARINC 653 in order to ensure dependability and non-interference between modules. The system allows the design of standalone field-programmable gate array (FPGA) hardware that integrates with PikeOS software as an efficient and safe RTOS
