在学习VxWorks I/O 系统功能的基础上，了解的基本I/O、缓冲I/O 及格式化I/O、文件描述符、标准输入/输出/错误设备的使用。对VxWorks I/O 系统中常用的API 有较为深入的理解。实践者对I/O 系统的理解和使用的熟练程度将影响后续实践环节进行顺利与否。通过I/O 系统API 与应用程序交互，能方便地对所调试的系统进行监控，是实时嵌入环境软硬件开发的主要手段之一。实现终端显示的秒表。精确到1/10 秒。可键盘控制暂停/继续计时/复位功能。

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。

Swfdec still is development software, but has also followed a rigid no-crashes-allowed policy. I believe it s stable enough now to be installed as a default plugin for people that can live with occasional crashes of their browser. But don t blame me if it does crash.

In this demo, I use the EM algorithm with a Rauch-Tung-Striebel smoother and an M step, which I ve recently derived, to train a two-layer perceptron, so as to classify medical data (kindly provided by Steve Roberts and Will Penny from EE, Imperial College). The data and simulations are described in: Nando de Freitas, Mahesan Niranjan and Andrew Gee Nonlinear State Space Estimation with Neural Networks and the EM algorithm After downloading the file, type "tar -xf EMdemo.tar" to uncompress it. This creates the directory EMdemo containing the required m files. Go to this directory, load matlab5 and type "EMtremor". The figures will then show you the simulation results, including ROC curves, likelihood plots, decision boundaries with error bars, etc. WARNING: Do make sure that you monitor the log-likelihood and check that it is increasing. Due to numerical errors, it might show glitches for some data sets.

I built the Superlist control whilst developing an RSS reader called FeedGhost. Although there are plenty of commercial grouped list controls available I wanted to have total control over the code and of course its usability. Superlist supports drag drop column customisation, grouping as well as handling thousands of entries smoothly. It s also highly customisable if you want to change its look and feel. In this article I ll explain how to use and extend the control in a demo project. If you download the source, you can find demo project under the Tests/SuperListTest directory.
