Description: 文章比较了H．264和AVS两个标准在运动补偿中运动矢量预测算法的差别， 提出了一种实现H．264 中
主档次(main pmille)下的第4级别(1evel 4)和AVS中的基准档次面向高清应用时运动矢量预测复用的硬件结构。
提出了一种新颖的缓存管理更新机制．极限情况下用于运动矢量的片上缓存大小减少了75％ 。用FPGA验证结果
表明资源占用情况是单独实现AVS的2．3倍，是单独同时实现两个标准的70％。能实现对1080i 30Hz高清图像实
时解码。-Article compares the H. 264 and AVS standards in the two motion compensation algorithm in the motion vector prediction difference, a realization of H. 264 in the main level (main pmille) under section 4 level (1evel 4) and AVS in the benchmark grade of application-oriented high-definition motion vector prediction reuse the hardware structure. A novel cache management update mechanism. Limit used for motion vectors on-chip cache size reduction of 75. The results show that the use of FPGA resources to verify the occupancy of a separate AVS realize 2.3 times, both individually and at the same time realize the standard 70. Can realize high-definition images to 1080i 30Hz real-time decoding.
