| Abstract(in English) | In this paper, we describe a feed-forward dynamic voltage/clock-frequency control method enabling low power MPEG4 on a multi-regulated voltage CPU with combining the characteristics of the CPU and the characteristics of the video encoding process. In the case that the CPU has Frequency-Voltage charcteristics of 1.80V@405 MHz to 1.06V@189 MHz, the proposed method reduces the power consumption to 38% at low motion sequences or 68% at high motion sequences comparing with the conventional software video encoding method. |
