摘　　要：以音频播放过程为例,阐述了数字音频信号在处理器Intel Xscale pxa270与音频芯片Philips UDA1341TS之间的数据传输过程.对音频电路进行硬件设计,并在Visual Studio 2005上进行软件编程,最终在支持win CE操作系统的Edukit-IV嵌入式实验平台上实现了数字音频的录入和播放等功能.By using the audio playing process as an example,the data transmission process of digital audio signal between the Intel Xscal 270 processor and the Philips UDA1341TS audio chip was introducee. The hardware of the audio circuits were designed and the software programming was operated in Visual Studio 2005.The audio recording and playing functions can be achieved in the Edukit-IV embedded experi-ment platform that supports the win CE operating system.
