| 摘 要： | 基于骏亿DMCU板开发的多媒体系统，采用多线程方式。通过DMCU板的GPIO扩展了USB通讯模块，利用义统ET44M210板实现与电脑高速通信，可以很方便的下栽视音频文件及将信息实时反馈。用户可以从本地（DMCU板）程序界面选择要使用的多媒体功能，同时在运行上位机程序时能对平台内多媒体文件进行更新和控制。平台的信息（如摄像头采集图像）也可以实时发放回上位机。

| Abstract: | The multimedia system based on JUNYI DMCU development kit adopts the multithreading.The system extends USB communication module through the GPIO of the DMCU board.One can easily download the vedio or audio files from the PC to the system and back feed the real-time information by connecting them with ETOM ET44M210.Customers can choose the multimedia function from the program menu.When the programs on the PC are running,the control and update of the multimedia files on the board are made at the same time.Of course,the infomation from the board(e.g.images captured by camera) also can be sent to PC in time. |
