The THERMAC project aims to investigate, develop, and validate emerging thermal-aware software-based techniques that will reduce operating temperature of avionic computing platforms in small aircraft transports. The project specifically targets the integration of multicore and GPU-based platforms in avionics from a thermal perspective. The expected impact of the improved thermal performance will improve dependability, computing performance, and will reduce size and weight of electronics due to relaxed dissipation requirements and the higher number of functionalities that can be integrated in the same computing platform.
