N2 - We present a fast motion estimation engine for the Unsymmetrical cross Multi-Hexagon-Grid-Search (UMHexagonS) algorithm used in H.264 video encoding. The architecture uses arrays of subtracting elements to maximize parallelism among search points on vertical or horizontal lines, and reduces sum of absolute differences (SAD) calculations. Performance is measured in terms of cycles required to encode Common Intermediate Format (CIF) video frames with 5 reference frames within a search range of 16. The number of cycles is reduced by around 99% compared with the JM 10.1 package running on a baseline Pentium 4 processor. The architecture thus achieves real time motion estimation at a clock speed of only 200MHz.
