针对每个结构模块的运动分析和功能需要，提出相关的结构模型，对重要的部件进行相关的设计计算，确定几何尺寸。

According to each structure module movement analysis and function, relevant structure model is set up and calculation is going on to definite geometry size for the important part.

然后对解码器进行复杂度分析，找出解码耗时的关键部分分别为运动补偿、反变换、环路滤波等模块。

Then analyses the complexity of AVS decoder and finds out the the critical modules are motion compensation, integer transform, quantization and loop filter.
