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 realtime 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 motion estimation architecture design is introduced. The architecture integrated the FS and the Edge Information Mode Decision (EIMD) + Predict Hexagon Search (PHS). With some reconfigurable issues, this architecture achieved the real-time specification with different power status.
