- Abstract
This paper first introduce the H.264 video codec standard briefly, then analyze the inter-frame motion estimation in H.264. After that we propose an optimaized algorithm and the corresponding architecture. A pipeline-architecture was proposed with scaled searching algorithm based on the analysis to the previous work and the consideration of the system requirement between chip area and performance. A pipelined architecture with two 1-dimension interpolation for fractional pixe ME was proposed to meet the needs of SHD 2160P video encoding, resulting in lower complexity and more throughout. Synthesized with Charted 0.13 m process, the design consumed 174.3K logic gates, with peak frequency of about 200MHz, and consumed less than 20mW at the power supply of 1.20V.
