Description: Buddy（伙伴）算法每次分配包含一个或者多个物理页面的内存块，页面以2的次幂的内存块来分配。首先搜寻满足请求大小的页面，它从满足当前申请大小的Buddy数据结构的m_ freePages域着手沿链来搜索空闲页面。如果没有这样请求大小的空闲页面，则它搜索两倍于请求大小的内存块。这个过程一直将持续到所有的Buddy 被搜索完或找到满足要求的内存块为。如果找到的页面块大于请求的块则对其进行分割以使其大小与请求块匹配。由于块大小都是2的次幂所以分割过程十分简单：空闲块（低地址）被连进相应大小的队列而这个页面块被分配给调用者。 释放时，先检查该块的伙伴的使用情况，如果没有被使用，则合并这对Buddy，再检查该两倍大小的块的Buddy，一直持续到合并后的块没有Buddy为止，并将之链到该大小的freepage队列中。-Buddy (partners) each allocation algorithm contains a number of physical pages or blocks of memory, two pages to the Powers of the block of memory to allocate. First of all search requests to meet the size of pages, from the application to meet the current size of the data structure Buddy 8 freePages domain proceed along the chain to search leisure pages. If no such request size spare pages, which then search request twice the size of a memory block. This process has to continue until all the Buddy Search End or were found to meet the requirements for the memory block. If found in the pages block greater than the requested block is divided in its size and make it the request block matching. As pieces are the two Powers So segmentation process is very simple : free block (low-address) was e

Description: 运动估计是视频压缩中帧间预测编码的关键技术之一，在各个压缩标准中都广泛使用了基于块的运动估计技术。由于运动估计通常具有较大的运算量，因此对压缩性能具有重要的影响。本文在分析了视频序列的特点和对现有的快速搜索算法深入理解的基础上提出了一种改进的快速运动估计搜索算法，通过实验表明该算法对压缩性能有了较好的改进。
-Video Compression interframe predictive coding one of the key technologies. in various compression standards has made extensive use of block-based motion estimation technology. As the motion estimation is usually larger amount of computation, so the compression performance has a significant influence. Based on the analysis of the video sequence and the characteristics of the existing Quick Search Algorithm in-depth understanding on the basis of a modified Quick search motion estimation algorithm, experiments show that the algorithm has better compression performance improvements.

Description: 视频序列运动矢量分布的中心偏移特性在运动估计中发挥重要的作用，但忽视了运动矢量分布的方向性。该文提出了非对称双十字形搜索(UDCS)算法，给出了在搜索的初始阶段使用小十字搜索模型对小的运动矢量搜索并在相继的搜索过程中使用具有方向性的十字形搜索模型对大运动矢量进行搜索的步聚。介绍了该算法的实现结构，并分析了该算法搜索性能。-Video sequence of motion vector distribution characteristics of the center offset is estimated in sports play an important role, but ignored the direction of motion vector distribution. This paper presents asymmetric double cross search (UDCS) algorithm, given the initial stage in the search using small cross english model of small motion vector search and the search process have been using a directional cross english model of large motion vector search步聚. Introduce the realization of the algorithm structure, and analyze the search performance of the algorithm.
