运动估值是视频压缩编码运算量最大的部分，与算法相应的搜索窗存储器结构设计十分重要。提出一种适于子采样望远镜快速搜索算法的存储结构。可进行大范围望远镜搜索，并保证处理单元流水线不空，无等待时间，具有运算效率高、带宽小等特点。已应用于单片MPEG2 MP@ML视频实时编码器的搜索引擎设计。

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 S WM architecture suitable for sub-sampled telescopic search is presented in this paper. It can perform large-range searching with no interrupted pipeline penal ty. Therefore the architectture has high computing efficiency and narrow I/O ba ndwidth. 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.
