  • Method of DVFS-power management and corresponding system
    Patent number: 11455433
    Abstract: In one embodiment, a system on chip includes a dynamic voltage and frequency scaling (DVFS) power supply, a secure environment, a non-secure environment, and a power supply management control module. The secure environment is configured to generate a secure instruction defining a permitted operating point of voltage and frequency for the DVFS power supply. The non-secure environment is configured to generate a request to modify the DVFS power supply, where the request to modify includes a voltage-frequency operating point. The power supply management control module is configured to scale the DVFS power supply to the permitted operating point, in response to the request to modify the DVFS power supply.
