摘　　要：提出了基于SoPC设计视频终端的方案,并在DE2开发板上利用NiosII软核处理器及操作系统进行了实现。该视频终端具有视频采集、JPEG编码和网络传输的功能。系统中的视频采集设备和JPEG编码设备作为两个自定制的外围设备,除了要完成这两个设备的硬件设计外,还要开发这两个设备的驱动,最终在整个SoPC系统和μC/OS-II操作系统下进行应用程序开发以实现NiosII处理器控制下的视频终端的功能。The program of a video terminal based on SnPC is proposed in this paper. The design is realized on DE2 board which is controlled by Nios II soft core CPU and Operation System（OS）, and has the functions of video acquiring, video encoding and network transmitting. The devices of video acquiring and video encoding in the system are two user-defined peripherals, so the hardware and driver designs about the two devices are required. Finally the video terminal which is controlled by Nios Ⅱ CPU is realized after developing the applications under the whole SoPC system and μC/OS-Ⅱ OS.
