Abstract
With the growing use of wearable and implantable medical devices, ensuring the reliability of embedded software is crucial for patient safety. These devices are susceptible to soft errors, and traditional single-bit fault models often fail to account for multi-bit faults, leading to either insufficient protection or excessive overhead. We introduce V-FAME, a lightweight and efficient vulnerability analysis framework for embedded healthcare systems. V-FAME uses machine learning and a multi-bit fault model to identify fault-sensitive code regions quickly and accurately. Unlike existing tools that focus on instruction-level analysis, V-FAME uses a basic block-level classification approach to significantly prune the fault space. Our experiments show V-FAME achieves a speedup of over 6.16x while maintaining an accuracy of over 80%. This framework supports reliable and cost-effective fault mitigation in medical applications.
