Abstract :
The multimedia system on the mobile is becoming universal, and the multimedia technology has made a significant progress. A mobile device generally with a limited power but is very powerful to support multimedia functions, such as the real-time video communication, movie watching, video and photo capture. In order to support this high computation complexity with the limited power, a power aware architecture is necessary. In a video system, motion estimation has the highest computation complexity. Therefore, in this paper, a concept of a power aware reconfigurable motion estimation architecture design for H.264 Encoder is introduced. This architecture combined several coding sizes and frame rates. With some reconfigurable issues, this architecture achieved the real-time specification with different power status.
