| 摘 要： | 运动估计是运动补偿技术的核心部分。本文在比较了VDSP中几种运动估计算法（光流分析法、块匹配法和象素递归法）的基础上，详细介绍了硬件复杂度较低、易于实现的块匹配法的典型电路。结合这种设计思路，设计出了具有良好前景的VDSP专用芯片。

| Abstract: | Motion estimation is the core technique of the motion compensation. Based on the comparison of several motion estimation algorithms,such as optical flow equation algorithm(OFA), block matching algorithm(BMA) and pixel recursion algorithm(PRA), a typical hardware circuit of BMA algorithms with low hardware complexity is showed in details. Using this technique a new VDSP ASIC has been designed. |
