An efficient adaptive method to perform dynamic voltage and frequency management (DVFM) for minimizing the energy consumption of microprocessor chips is presented. Instead of using a fixed update interval, the proposed DVFM system makes use of adaptive update intervals for optimal frequency and voltage scheduling. The optimization enables the system to rapidly track the workload changes so as to meet soft real-time deadlines. The method, which is based on introducing the concept of an effective deadline, utilizes the correlation between consecutive values of the workload. In practice because the frequency and voltage update rates are dynamically set based on variable update interval lengths, voltage fluctuations on the power network are also minimized. The technique, which may be implemented by simple hardware and is completely transparent from the application, leads to power savings of up to 60% for highly correlated workloads compared to DVFM systems based on fixed update intervals
