SafeDM

SafeDM is a lightweight safety solution that monitors two independent processor cores to detect faults without duplicating every operation. It compares compact signatures of their activity and raises alerts when unusual differences appear. This approach detects errors early while using far less hardware and power than traditional methods. It works without modifying existing software or tools, supporting portability across systems. By reducing duplication and energy use, SafeDM offers a more efficient way to improve reliability in safety-critical applications.
