摘　　要：设计一种可应用于多模视频解码SoC的运动矢量预测器,能灵活支持MPEG-4AVC/H.264和AVS视频编解码标准。介绍了设计特点,并以Xilinx Virtex 2系列XC2V6000为目标器件进行仿真,结果表明该设计能正确支持1080i50Hz高清码流的实时解码。A motion vector predictor is proposed in this paper, which can be applied in multi-mode video decoding SoC design. The key characteristic of this device is that it can support both MPEG-4AVC/H,264 and AVS decoding standard flexibly. Some important points of the design are introduced and the result of synthesis is given with Xilinx Virtex2：XC2V6000 as target device. The simulation performance shows that our design can effectively support the real-time decoding of 1080i 50 Hz HD stream.
