【摘要】：龍芯是中國科學(xué)院計算所自主研發(fā)的高性能通用CPU,這改寫了我國無“中國芯”的歷史。繼2002年研制成功龍芯1號處理器芯片后,近些年分別研制成功龍芯2B、龍芯2C、龍芯2E、龍芯2F、龍芯3A,且每個芯片的性能都是前一個芯片的3倍,實現(xiàn)了通用處理器設(shè)計的跨越發(fā)展。此外為了能使我國自主可控的芯片推向市場,在江蘇成立了江蘇中科夢蘭電子科技有限公司,它是自主信息產(chǎn)業(yè)領(lǐng)軍企業(yè)之一,是我國第一款高性能通用CPU,龍芯的產(chǎn)業(yè)基地和龍頭企業(yè),致力于用自主創(chuàng)新技術(shù)打造行業(yè)信息化整體解決方案。 隨著龍芯在江蘇教育信息化中的快速發(fā)展及普及,使得日常維護(hù)和售后工作面臨很大的難題。本文根據(jù)公司提供的機(jī)器中預(yù)安裝的操作系統(tǒng)需要具備升級和恢復(fù)的能力,按照軟件工程學(xué)的方法來進(jìn)行設(shè)計和開發(fā)了一個新的維護(hù)工具——升級還原系統(tǒng)。 本文首先對系統(tǒng)升級進(jìn)行了詳細(xì)的需求分析,研究了使用龍芯平臺對設(shè)計升級還原系統(tǒng)的可行性,并對針對需求產(chǎn)生的升級還原系統(tǒng)所需要的各種組件進(jìn)行分析以及功能設(shè)計；在需求分析的基礎(chǔ)上對升級還原系統(tǒng)進(jìn)行詳細(xì)的設(shè)計：包括文件系統(tǒng)、配置設(shè)置、界面設(shè)置、異常處理、日志系統(tǒng)等方面,最后確定了界面和功能模塊,成功完成了服務(wù)器端和客戶端的開發(fā)。實現(xiàn)了在龍芯平臺上運行updateserver客戶端程序,并能通過制作LiveUSB系統(tǒng)來完成升級、還原和軟件安裝等功能。
[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.
