一种新型全搜索运动估计IP核设计

The New Design of Full Search Motion Estimation IP Core

为了降低全搜索运动估计算法带来的巨大计算量,提高运动估计计算速度,提出了一种新型的用于全搜索运动估计硬件结构。该硬件结构能实时地通过全搜索运动估计来搜索每个像素块最佳的匹配运动向量,并通过改进搜索窗缓存,获得了较高的运算速度增益并有效地降低了电路功耗。

In this paper, an improved full search motion estimation hardware structure is proposed to reduce the enormous amount of computation and improve computing speed motion estimation. The hardware structure can search for the best match motion vectors of each pixel block through full motion estimation, and through improved search window cache,, access to a higher gain faster and effective reducing the power circuit.
