摘要
H.264作为最新的视频编码标准具有很高的压缩性能,对它的研究具有重要的意义。根据H.264的变换量化算法设计一种基于FPGA的高性能变换量化处理结构,该结构采用流水线操作和分时复用技术。结果显示,该设计既节省了资源,又保证了效率;能够同时处理整个4×4块的全部16个残差输入数据,并在236个时钟内完成对1个宏块的残差数据从输入到反变换输出重建值的完整变换量化过程。它的处理速度和性能大大提高,可用于硬件加速。
As the newest video code standard, H. 264 shows much good performance in video compression. It is very important to study H. 264. According to the algorithm of H. 264, a good performance architecture of transform and quantization based on FPGA is designed. This architecture adopts pipeline strategy and Time Division Multiplexing（TDM） technology. The results show it can calculate sixteen residual inputs of one 4 × 4 block simultaneously and perform the processing course of a micro block from residual input to inverse quantization output in two hundred and thirty six cycles. The processing speed and performance of this design are improved greatly, and it can be used for hardware speeding.
