Reconfigurable Architecture Design for H.264 Motion Estimation and 3D Graphics Rendering

Abstract

As digital mobile communication becomes popular, data processing capability that includes H.264 and 3D graphics will be essential for future mobile terminals. In this paper, reconfigurable architecture is described, which can perform either notion estimation for H.264 or rendering for 3D graphics. In motion estimation for variable block sizes, disable approximate unit has been designed to make early termination of absolute difference computation when the termination does not affect the performance. In 3D rendering, midline traversal algorithm is used for parallel processing. Memories are partitioned for sharing and selective power shutdown. Processing elements are also shared to reduce the chip area by 7%.
