摘　　要：设计了一种适合于AVS的自适应环路滤波器。为解决计算复杂度高的问题,通过片内缓存管理方式和流水线设计,解决了环路滤波的硬件实现时速度慢的问题,使得效率提高,达到了实时解码的要求。最后采用Verilog语言进行设计和仿真。An self-adapted loop filter based on AVS is designed in this paper. By using the appropriate management of bufferon chip and pipelining design, the processing speed and efficiency are greatly improved, and thus solve the problem of high calculating complexity, and meet the requirements of real-time decoding. Finally, the design is simulated by using Verilog language.
