This paper proposes an off-line dynamic voltage scaling (DVS) scheme that can be integrated with EDF$$^{(k)}$$(k), which is a global real-time scheduling algorithm for symmetric multiprocessor systems. The scheme computes the static execution speed for each individual task assuming the task's worst-case execution. Based on the individual speed, it determines static dual speeds off-line for each task to make use of the gap between actual execution demand and the worst-case execution demand. The simulation results show that the proposed scheme combined with an existing online DVS technique can reduce energy consumption by up to 37 % compared with a uniform speed technique when the number of processors is 32.
