摘要
基于ARM7内核S3C44B0X微处理器内置IIS总线和音频数模转换芯片CS4334,详细设计了S3C44B0X内置IIS总线接口和芯片CS4334的连接方法,搭建了以二者为基础的嵌入式工作平台.基于此工作平台,实现了wave文件播放,并给出了具体实现程序.
Based on the micro processor S3C44B0X IIS-Bus and the audio digital-to-analog chip CS4334,the interface and connecting approach among them are detailed designed,and the embedded worktable is putted up on basis of them. The wave audio files are played well based on the worktable.In order to show the playing process clearly,the program is presented in this paper.
