【摘要】：龙芯是中国科学院计算所自主研发的高性能通用CPU,这改写了我国无“中国芯”的历史。继2002年研制成功龙芯1号处理器芯片后,近些年分别研制成功龙芯2B、龙芯2C、龙芯2E、龙芯2F、龙芯3A,且每个芯片的性能都是前一个芯片的3倍,实现了通用处理器设计的跨越发展。此外为了能使我国自主可控的芯片推向市场,在江苏成立了江苏中科梦兰电子科技有限公司,它是自主信息产业领军企业之一,是我国第一款高性能通用CPU,龙芯的产业基地和龙头企业,致力于用自主创新技术打造行业信息化整体解决方案。 随着龙芯在江苏教育信息化中的快速发展及普及,使得日常维护和售后工作面临很大的难题。本文根据公司提供的机器中预安装的操作系统需要具备升级和恢复的能力,按照软件工程学的方法来进行设计和开发了一个新的维护工具——升级还原系统。 本文首先对系统升级进行了详细的需求分析,研究了使用龙芯平台对设计升级还原系统的可行性,并对针对需求产生的升级还原系统所需要的各种组件进行分析以及功能设计；在需求分析的基础上对升级还原系统进行详细的设计：包括文件系统、配置设置、界面设置、异常处理、日志系统等方面,最后确定了界面和功能模块,成功完成了服务器端和客户端的开发。实现了在龙芯平台上运行updateserver客户端程序,并能通过制作LiveUSB系统来完成升级、还原和软件安装等功能。
[Abstract]:Longson is a high performance universal CPU, developed independently by the Institute of Computing of the Chinese Academy of Sciences, which rewrites the history of China without "China Core". Following the successful development of the processor chip Ronson 1 in 2002, in recent years we have successfully developed the core 2B, the dragon son 2C, the dragon son 2E, the dragon son 2F, the dragon son 3A.The performance of each chip is three times that of the previous chip. The design of general purpose processor is developed by leaps and bounds. In addition, in order to bring our own controllable chips to the market, Jiangsu Zhongke Meng Lan Electronic Technology Co., Ltd. was established in Jiangsu Province. It is one of the leading enterprises in independent information industry and the first high performance universal CPU, in China. Longson's industrial base and leading enterprises are committed to creating the overall solution of industry informatization with independent innovation technology. With the rapid development and popularization of Longson in Jiangsu education informatization, daily maintenance and after-sale work are facing great difficulties. According to the capability of upgrading and restoring the pre-installed operating system in the machine provided by the company, this paper designs and develops a new maintenance tool, the upgrade restore system, according to the method of software engineering. In this paper, the system upgrade is analyzed in detail, and the feasibility of designing the upgrade and restore system by using the Godson platform is studied, and all kinds of components needed for the upgrade and restore system are analyzed as well as the function design. On the basis of requirement analysis, the upgrade and restore system is designed in detail, including file system, configuration setting, interface setting, exception handling, log system and so on. Finally, the interface and function module are determined. Successfully completed the development of the server and client. The updateserver client program is implemented on the Godson platform, and the functions of upgrade, restore and software installation can be accomplished by making LiveUSB system.
