摘要
AVS-P7(即AVS-M)是AVS系列标准中的第七部分移动视频编码标准。提出一种基于AVS-P7运动补偿单元的VLSI结构,采用改进的片上RAM读写机制和插值计算单元结构,以较少内存访问次数和较低的硬件代价,满足SD数据流实时解码的要求。
AVS-P7 is a kind of video compress standard which was specially designed for mobile graphic devices. We bring forward a kind of VLSI structure of interpolation calculation unit based on AVS-P7 in the paper. We use the improved RAM read/write mechanism and filter design to make it support the SD realtime decoding with the less memory access and smaller area.
