练习并掌握多任务实时操作系统下tASK 调度、tASK 间主要通信手段(信号量、消息队列等)、RISC 处理器 I/O 端口控制等内容,并形成嵌入式实时应用软件的良好编程习惯。创建多tASK,为每个tASK 创建私有的Message Queue,每个tASK 只通过自己的私有Message Queue 接收消息;tASK 间消息通信通过向对方私有MessageQueue 发送消息完成。 tASK1:管理tASK。负责系统启动时同步系统中其他tASK 的启动同步,利用信号量的semFlush()完成。同时接收各tASK 的告警信息,告警信息需编号以logmsg 方式输出。本tASK 负责系统结束时的tASK 删除处理。 tASK2:console 命令行接收tASK。接收并分析console 发来的命令行及参数。自行设置5 种以上命令,并根据命令的内容向tASK3 或/及tASK4 发送激励消息。同时实现系统退出命令,使系统采用适当方式安全退出。收到非法命令向tASK1告警。 tASK3:Led 控制tASK。接收Led 控制消息(命令),自定义Led 显示方式表现命令执行情况。本tASK 应负责led 相关I/O port 初始化。收到非法led 控制命令向tASK1 告警。 tASK4:console 输出tASK。接收需打印输出的字串消息(命令),输出到console。收到长度为0 或超常字串向tASK1 告警。

一个利用tASK和电平敏感的always块设计比较后重组信号的组合逻辑的实例。可以看到,利用tASK非常方便地实现了数据之间的交换,如果要用函数实现相同的功能是非常复杂的;另外,tASK也避免了直接用一般语句来描述所引起的不易理解和综合时产生冗余逻辑等问题。

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币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.
