To achieve power and performance-efficient capabilities for various computing demands like gaming, browsing, etc., the CPU typically features multiple cores. In one study [1], the CPU scheduling mechanism optimizes the allocation of tasks to each core of the CPU based on predicted available power budgets. Further balancing of power and thermal distribution across the multiple cores is done to ensure sustainable performance. To ensure system stability, power calculation techniques at runtime consider factors of voltage, frequency and leakage, including pessimistic elements such as voltage guard band. As such, an on-die
