Abstract: Based on analysis of advanced coding of Audio Video coding Standard（AVS），this paper introduces the design of intra prediction.The 8×8-block level pipeline is adopted to improve the real-time throughput.Sliding window is designed to fetch reference pixels.Eight parallel processing elements are employed to handle eight pixels.Plane mode carries out prediction based on scheme of systolic array.The design is based on the Verilog Hardware Design Language（HDL）.The simulation and synthesis results indicate that the design meets the requirement.

摘要： 分析了先进音视频编码标准（Audio and Video Standard，AVS）的帧内预测算法，提出了实现自适应帧内预测的硬件架构。该硬件架构采用8×8块级自适应流水线，利用滑动窗口获取片上存储器中的参考样本，使用8个并行的处理单元（PE）计算预测值，用脉动阵列实现复杂色度Plane模式预测值的计算。基于Verilog HDL硬件描述语言实现设计并进行功能验证，仿真和综合结果表明设计符合要求。
