摘要
研究了AVS标准的帧间预测运动补偿的相关算法,并提出了一个硬件设计结构,可以对AVS标准的P,B帧下的各种块模式进行运动补偿。通过有效的流水控制可以使该设计达到AVS基准档次4.2级别(720×576,4︰2︰2,30f/s)的实时预测,通过有效的结构设计和优化措施大大提高了速度,并节约了硬件资源。
In this paper, the algorithm of motion compensation in AVS standard is researched and a hardware architecture for implementing motion eompensation in AVS decoder system is proposed. This architecture can process blocks with different block modes of P/B frame in AVS standard. With efficient pipeline control, this arohitecture can support real-time motion compensation of AVS JiZhun profile @ 4.2 level （720×576, 4 ： 2 ： 2, 30 frames per second）. This architecture can work in a higher clock rate and is also cost-saving with efficient optimized implementation.
