摘要
阐述了音频解码器的基本模式和AMR-WB+解码系统总体框架以及解码流程,实现了AMR-WB+解码算法。文章还应用了FPGA开发套件EDK开发工具包,提出了基于FPGA平台的解码器结构设计。进行了在FPGA平台上完成解码器关键算法移植,并就在移植过程中出现的特殊情况进行针对性解决。
The AMR- WB ＋ audio decoder system is introduced, including the codec standard, framework and decoding process of the AMR - WB ＋ decoder. The AMR - WB ＋ algorithm are realized. The EDK Development Kit is used to set up the embedded system and to port ANSI C from PC to FPGA platform. The porting steps are given. Problems and solutions during the debugging are also given. Finally, during the debugging, some problems and solutions of the AMR -WB ＋ decoding algorithm based on FPGA platform are given.
