摘　　要：选用Samsung公司的S3C2442B型随机存储器(ARM)微处理器和Wolfson公司的WM8983音频编解码(CODEC)芯片设计实现一种基于串行数字音频总线(IIS)嵌入式音频系统,给出了相关硬件电路的设计,并介绍了该音频系统基于WinCE操作系统的驱动程序的实现。所设计的嵌入式音频系统已成功应用于手持式卫星导航用户终端设备之中,具有较高的通用性及参考价值。As the development of mobile navigation products, it puts torwara mgner requirements for using embedded audio system to implement voice navigation, broadcasts position and realize other interactive features. This paper designs embedded audio system based on IIS bus by using Samsung＇s ARM processor S3C2442B and Wolfson＇s WM8983 stereo audio codec chip,describes the hardware designing, introduces the driver implementation of this embedded audio system based on real time operation system WinCE. The audio system which this paper introduced have been used to a satellites navigation mobile produces , and it＇ s general and can be a good reference.
