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.
