Dynamic Power Management and Dynamic Voltage Scaling in Real-time CMP Systems

Real-time embedded systems need reducing power consumption while still maintaining high performance. Dynamic power management (DPM) and dynamic voltage scaling (DVS) are effective control techniques to reduce the energy consumption. We present a real-time energy saving scheduling (RESS) algorithm using DPM and DVS to reduce the energy cost for chip multiprocessor (CMP) systems. The simulating experiment results indicate that our algorithm can save system energy cost with little system performance degradation.
