FPGA实现AVS编码器P帧全过程

以数字音视频编码技术标准(Audio Video coding Standard,AVS)为依据,通过对该算法全过程的分析,并结合FPGA硬件平台的结构特点,设计了预测、DCT变换和反DCT变换、量化和反量化、熵编码的全过程。利用FPGA开发工具ISE10.1和仿真工具ModelSim SE 6.2b,并通过Xilinx公司xc5vlx110t-1ff1136平台验证,完成了AVS编码标准P帧从设计到实现的全过程。填补了AVS编码器P帧在FPGA上未实现的空白,同时促进了AVS在FPGA上的发展,并对AVS+和AVS 2发展起到关键性作用。

Implementation of the Entire Process of AVS Encoder P-Frame based on FPGA

Based on digital audio and video technology standard (AVS, Audio and Video coding Standard), the entire process of prediction, DCT and inverse DCT, quantization and dequantization and entropy encoding is designed through analyzing the entire process of this algorithm and combining the structural characteristics of FPGA hardware platform in this paper. Simulated with FPGA development tool ISE10.1 and simulation tool ModelSim SE 6.2b and validated with Xilinx xc5vlx110t-1ff1136 platform, the whole process of design and implementation of AVS encoding standard P frame is achieved. This design bridges the gap unfilled in the FPGA implementation of AVS encoder P frame, promotes the development of AVS on FPGA and plays a crucial role in the development of AVS and AVS2.
