  • Devices, systems, and methods for detecting and mitigating silent data corruptions via adaptive voltage-frequency scaling
    Patent number: 12399772
    Abstract: An exemplary computing device includes a plurality of circuits and/or a plurality of in-situ monitors configured to generate outputs that indicate one or more operating conditions of the circuits. The computing device also includes a system management unit configured to detect a potentially faulty voltage-to-frequency ratio implemented by one of the circuits based at least in part on one or more of the outputs. The system management unit is also configured to modify the potentially faulty voltage-to-frequency ratio based at least in part on one or more of the outputs. Various other devices, systems, and methods are also disclosed.
    Type: Grant
    Filed: April 3, 2024
    Date of Patent: August 26, 2025
    Assignee: Advanced Micro Devices, Inc.
    Inventors: Divya Madapusi Srinivas Prasad, Sudhanva Gurumurthi, Yasuko Eckert, Jeffrey Richard Rearick, Sankaranarayanan Gurumurthy, Amitabh Mehra, Shidhartha Das, Alex W. Schaefer, Vikram Ramachandra, Vilas Sridharan
