- To reduce the power consumption of portable devices, many researches have been conducted on the dynamic voltage scaling(DVS) and dynamic power management(DPM). Embedded systems such as DMBs, PMPs and PDAs require long battery life without reducing their performance. Also, power consumption is the most important factor in ubiquitous environment. Most researches are focused on power saving methods by hardware circuits. One of them is DVS, which has proven as a highly effective technique to reduce dynamic power consumption. But, software design and control should be considered to minimize the total energy consumption. This paper presents a power management design and implementation for embedded multimedia systems by guaranteeing QoS. The implemented results show that the system saves the total power consumption up to 5% compared with the DVS on the experiment board. ©2007 IEEE.
