| 摘 要： | 以XC2V3000为核心处理芯片，AD1671为模数转换芯片，设计极紫外相机的数据处理系统，实现对相机原始科学数据的采集、原始数据校正、原始数据到图像数据的换算、数据缓存等功能。为增加系统对单粒子效应的抵抗力，在有效数据之间插入标识数据，取代控制信号的移位延时，避免长链路移位寄存器的使用，增强系统稳定性。

| Abstract: | This paper describes the design and implementation of the data dampling and drocessing system of EUV camera,using XC2V3000 as main processor,AD1671 as the analog-to-digital converter.The system implements functions such as acquisition of original data of the camera,rectification of the original data,conversion to image data,and data buffering.In order to enhance the resistance against single event effect,long line shift-registers are avoided.Tag data are inserted between valid data,instead of the delay of c... |
