摘要：
Dynamic Voltage Scaling (DVS), which adjusts the clock speed and supply voltage dynamically, is is being increasingly used for power management in embedded systems. Energy is a scarce resource in embedded real-time systems and energy consumption must be carefully balanced against real-time responsiveness. In this paper, we address the problem of variable execution time in tasks under the FPPT scheduling policy. Our approach exploit the stochastic data to develop the intra.-task voltage scheduling, experiments show on an average 21%similar to 47% energy gains over usual DVS techniques.
