嵌入式系統(tǒng)中備份/恢復技術(shù)的設計

在深入研究了嵌入式系統(tǒng)特點的基礎(chǔ)上，分析了備份/恢復軟件的設計思想、系統(tǒng)功能及特點，并運用面向?qū)ο蟮能浖こ谭椒ㄍ瓿闪塑浖到y(tǒng)的總體設計，定義各個功能模塊，描述了業(yè)務邏輯和分析了備份/恢復的過程，該方法簡單、實用，占用系統(tǒng)資源少，具有良好的魯棒性、可移植性和擴展性。并以WindowsCE.NET 和個人數(shù)字助理(Personal Digital Assistant，PDA)為軟硬件平臺實現(xiàn)了該軟件。

Abstract: On the basis of deep research on characteristic of embedded system, multithreaded and dynamic link libraries technologies. According to the design concepts, system functions and characteristic of Backup/Restore are analyzed, and its holistic design is finished, every functional module is defined, the service logic is described and the procedure of backup/restore is analyzed. The solution is simple and practical, needing a little system resource, and it has good robustness, scalability and portability. And then realize this software system based on Windows CE.NET and PDA software and hardware platform.
