摘　　要：基于SpaceWire总线技术设计是由模拟综管设备、模拟相机设备、模拟数传设备和SpaceWire路由器组成的网络图像传输演示系统。针对设备中采用的ARM+FPGA架构,移植u-boot-2010.09和Linux-2.6.33作为设备软件架构的bootloader和嵌入式操作系统,阐述在Linux操作系统下FPGA设备驱动程序实现方法,编写基于MJPG-streamer视频服务器软件的SpaceWire网络服务程序,模拟了相机设备采集的图像通过SpaceWire网络传输到数据显示平台。A network image transmission demonstration system which consists of analog comprehensive management facility,analog data transmission facility ,analog camera facility and SpaceWire router is designed by using SpaceWire. According to the architecture of ARM and FPGA used in the facility, the u-boot-2010.09 and Linux-2. 6. 33 are transplanted as the bootloader and the embedded operation system in the software system ,the implementation of the FPGA device driver in the embedded Liuux system is discussed, the SpaeeWire net server program is written based on a video server software MJPG-streamer. The demonstration system simulates image transmission from analog camera facility to display platform by SpaceWire.
