| Abstract: | As a frontier technology in aerospace data bus, SpaceWire is high-speed and high reliability, and could be selected for constructing the new generation of onboard data processing network. Being part of demonstration and testing work for SpaceWire, on the embedded development platform based on Linux ＆ ARM, CMOS camera was used to simulate the image capture unit in on-board electronic systems. A method to implement the image capture and display was raised, which can improve the efficiency of image capture and display. Then it was focused on how to implement image capture and display from CMOS camera. The running result showed that SpaceWire could transmit the image data efficiently and that SpaceWire could offer increased bandwidth for satellite data system onboard. |
