摘要
本文设计了一种基于可编程片上系统(SOPC)技术的嵌入式数字音频录放系统方案.该系统通过在FPGA芯片上配置NiosII软核处理器和相关的接口模块来实现嵌入式系统的主要硬件结构,并结合系统的软件设计来控制音频芯片TLV320AIC23.实现了音频信号的A/D、D/A转换、存储、回放等功能.由于采用了SOPC和DMA控制技术,该系统具有设计灵活、扩展性好等优点.
This paper designed an embedded digital audio recording and replaying system on SOPC technology, By configuring NiosⅡ soft core CPU and some corresponding interface modules on a PFGA to construct an embedded system＇s hardware ,and combining software programming to controlling audio IC TLV320AIC23 system realized A/D, D/A conversion,thus saving and replaying of audio signal. Due to using the SOPC and DMA technology ,the system had high design flexibility and good expansibility.
