operating system access method 中文意思是什麼
operating system access method
解釋
操作系統存取法-
The concern is that the timer method itself - which probably ends up needing to go down to the operating system level to get access to a timer - adds some overhead, and if the timer method overhead is too large or the method is called too often, it s going to seriously distort the timing measurements
的這些問題，還有另一個使用任何類型的計時器方法監視程序執行都會有的問題。這個問題是計時器方法本身可能要深入操作系統才能訪問計時器這增加了一些開銷，如果計時器方法開銷過大（或者方法調用過于頻繁） ，那麼就會嚴重扭曲計時測量。 -
Firstly upon the real - time operating system rex, we study the module of ui task, adopt the in - level finite state machine mechanism, and give the total architecture design of the ui task, at the same time, realize the functional routines of the application, the definition of data structure, the design of interface etc ; then, we study the access strategy design of flash data and the display implementation design of lcd ; and study multi - language mechanism, design and implement text input method and display of multi - language ; finally, it evaluates the analysis and design of embedded software and makes a summary
同時，設計開發了一些功能模塊，包括數據結構定義，各種介面實現等。然後，研究了以flash為存儲介質，對數據的存儲管理的實現;以lcd為顯示媒介，對數據的顯示管理的實現。接著研究了移動終端的多語言機制，設計並實現了多語言文本的輸入法及字元顯示功能;最後，本文對cdma移動終端嵌入式軟體的分析、設計進行了評估與總結，並對未來的工作進行展望。 -
What ' s more, with fundamental research, the following solutions were put forward : database connectivity technology, which can help to implement this system which works in client / server mode, the way of using ole ( object linking and embedding ) to solve the storage and retrieval problems of blob ( binary large object block ) data type and the method of directly giving the database system ' s operating purviews to right users with the application of dbms ' s authentication mechanism, which help to control database ' s access
這些關鍵技術包括數據庫連接技術，以實現客戶/服務器模式下的數據庫開發；用ole技術解決大文本數據存取問題；結合dbms自身鑒別機制，將數據庫系統權限賦予用戶，以控制用戶對數據的訪問。最後，本文對南京物流公司管理信息系統的開發工作進行了總結，並展望了開發運輸類公司mis的發展方向。
