練習并掌握多任務實時操作系統下Task 調度、Task 間主要通信手段(信號量、消息隊列等)、RISC 處理器 I/O 端口控制等內容,并形成嵌入式實時應用軟件的良好編程習慣。創建多Task,為每個Task 創建私有的Message Queue,每個Task 只通過自己的私有Message Queue 接收消息;Task 間消息通信通過向對方私有MessageQueue 發送消息完成。 Task1:管理Task。負責系統啟動時同步系統中其他Task 的啟動同步,利用信號量的semFlush()完成。同時接收各Task 的告警信息,告警信息需編號以logmsg 方式輸出。本Task 負責系統結束時的Task 刪除處理。 Task2:console 命令行接收Task。接收并分析console 發來的命令行及參數。自行設置5 種以上命令,并根據命令的內容向Task3 或/及Task4 發送激勵消息。同時實現系統退出命令,使系統采用適當方式安全退出。收到非法命令向Task1告警。 Task3:Led 控制Task。接收Led 控制消息(命令),自定義Led 顯示方式表現命令執行情況。本Task 應負責led 相關I/O port 初始化。收到非法led 控制命令向Task1 告警。 Task4:console 輸出Task。接收需打印輸出的字串消息(命令),輸出到console。收到長度為0 或超常字串向Task1 告警。

一個利用Task和電平敏感的always塊設計比較后重組信號的組合邏輯的實例。可以看到,利用Task非常方便地實現了數據之間的交換,如果要用函數實現相同的功能是非常復雜的;另外,Task也避免了直接用一般語句來描述所引起的不易理解和綜合時產生冗余邏輯等問題。

The Task of clustering Web sessions is to group Web sessions based on similarity and consists of maximizing the intra- group similarity while minimizing the inter-group similarity. The first and foremost question needed to be considered in clustering W b sessions is how to measure the similarity between Web sessions.However.there are many shortcomings in traditiona1 measurements.This paper introduces a new method for measuring similarities between Web pages that takes into account not only the URL but also the viewing time of the visited web page.Yhen we give a new method to measure the similarity of Web sessions using sequence alignment and the similarity of W eb page access in detail Experiments have proved that our method is valid and e幣cient.

Visual tracking is one of the key components for robots to accomplish a given Task in a dynamic environment, especially when independently moving objects are included. This paper proposes an extension of Adaptive Visual Servoing (hereafter, AVS) for unknown moving object tracking. The method utilizes binocular stereo vision, but does not need the knowledge of camera parameters. Only one assumption is that the system need stationary references in the both images by which the system can predict the motion of unknown moving objects. The basic ideas how we extended the AVS method such that it can track unknown moving objects are given and formalized into a new AVS system. The experimental results with proposed control architecture are shown and a discussion is given.
