| Abstract: | Motion estimation is a major computational part of video encoding. The architecture of the search window memory (SWM) is of equal importance with the algorithm. A SWM architecture suitable for sub sampled telescopic search is presented in this paper. It can perform large range searching with no interrupted pipeline penalty. Therefore the architectture has high computing efficiency and narrow I/O bandwidth. It has been used in the design of the search engine for a single chip MPEG2 (moving picture experts group) MP@ML video real time encoder. |
