摘　　要：基于SOPC技术的系统设计具有极大的灵活性,因而在许多电子设计中被广泛的采用,本文设计了一款基于Nios II嵌入式处理器的音频播放器,详细介绍了音频播放器在Nios II处理器上的实现方法,通过实现SD卡、解码芯片——VS1053B等硬件的驱动,最终在FPGA上成功运行。System design based on SOPC technology has great flexibility, so it has been widely used in many electronic designs. This paper designed an audio player based on embedded Nios II processor, introduced the implementation method of the audio player on Nios II processor in detail. By implementing the drivers of hardware such as SD card,decoding chip ——VS1053B, it runs successfully on FPGA eventually.
