| Abstract(in English) | Dynamic Freqency Scaling (DFS) and Dynamic Voltage Scaling (DVS) are promising techniques for embedded systems, which scale freqency and voltage, in order to reduce the energy consumption. However, most of existing DFS techniques for hard real-time system are not practical, since they compute the freqency scaling every time contexts are switched. In this paper, we propose a DFS technique for soft real-time systems, which is able to provide significant energy savings with controling the deadline miss ratio in a constant range. Also, the proposed DFS technique is more practical than the existing techniques, since it controls the freqency only at a certain period. The simulation experiments demonstrate that the proposed technique is able to save up nearly as much energy as the exsisting techniques with controling the deadline miss ratio in a constant range. |
