A method and apparatus for power and thermal management for multiple processing cores are disclosed. Existing dynamic voltage and frequency scaling (DVFS) approaches typically perform localized management for individual cores, such as a central processing unit (CPU) or a graphics processing unit (GPU), resulting in suboptimal overall power consumption and thermal throttling. The disclosed energy manager addresses this by performing energy management across at least two computing cores executing a hybrid workload with a shared execution deadline. The energy manager acquires historical performance data to predict the execution time and total power consumption for a plurality of voltage and frequency combinations. An optimal combination is selected that minimizes the total predicted power consumption while meeting the deadline. The system further determines a thermal constraint, such as a thermal power budget, and restricts the available voltage and frequency combinations, ensuring continuous operation within safe thermal limits while improving power efficiency.
