The project AR2SEC (High-Performance Architectures for Critical Sectors), led by GTD Science, Infrastructures & Robotics, has successfully developed a RISC-V–based platform built around the Safety Island SoC (SISoC) concept — an architecture designed to combine functional safety, reliability, and computational performance across critical domains such as aeronautics,automotive, and energy.
The SISoC approach integrates a high-performance computing system with a dedicated safety island, ensuring deterministic and safe operation even under demand ingreal-time conditions. This innovative design allows applications of mixed criticality to coexist securely within the same embedded environment, meetingstringent certification standards across industries.
To validate the concept and demonstrate its adaptability, the consortium selected threeverticals — aeronautics, automotive, and fusion energy — as representative use cases. Each sector served as a testbed to evaluate performance, safety, and integration capabilities.
The AR2SECconsortium brought together leading technology partners:
Clue Technologies, FENTISS, Technica Electronics, the Barcelona Supercomputing Center (BSC), and the Universidad Politécnica de Madrid (UPM).
Together, these organizations have achieved significant progress inhigh-performance and safety-critical computing, reinforcing Europe’s technological sovereignty in semiconductors and embedded systems.
For GTD,the project has strengthened its know-how in SoC design, FPGA technology, and virtualization for embedded environments, as well asits capabilities in real-time communications, deterministic networking,and digital twin visualization. These advances position GTD to deliver innovative, high-reliability solutions for future critical infrastructures.
