Developed and integrated a VCORE Dynamic Voltage and Frequency Scaling (DVFS) driver for the MT8196 platform within the zephyrproject-rtos/trusted-firmware-a repository. This work focused on embedded systems and low-level programming in C, enabling the platform to dynamically adjust VCORE and DRAM voltages and frequencies based on system activity. By introducing runtime power management, the driver reduces idle power consumption and extends battery life, laying the groundwork for future power optimizations. The implementation emphasized code maintainability and clear documentation, ensuring that the new power management capabilities can be enhanced and reused across similar platforms in subsequent development cycles.
