VLAN(Virtual local Area Network)的中文名为"虚拟局域网"。VLAN是一种将局域网设备从逻辑上划分成一个个网段，从而实现虚拟工作组的新兴数据交换技术。这一新兴技术主要应用于交换机和路由器中，但主流应用还是在交换机之中。

This white paper discusses how market trends, the need for increased productivity, and new legislation have accelerated the use of safety systems in industrial machinery. This TÜV-qualified FPGA design methodology is changing the paradigms of safety designs and will greatly reduce development effort, system complexity, and time to market. This allows FPGA users to design their own customized safety controllers and provides a significant competitive advantage over traditional microcontroller or ASIC-based designs. Introduction The basic motivation of deploying functional safety systems is to ensure safe operation as well as safe behavior in cases of failure. Examples of functional safety systems include train brakes, proximity sensors for hazardous areas around machines such as fast-moving robots, and distributed control systems in process automation equipment such as those used in petrochemical plants. The International Electrotechnical Commission’s standard, IEC 61508: “Functional safety of electrical/electronic/programmable electronic safety-related systems,” is understood as the standard for designing safety systems for electrical, electronic, and programmable electronic (E/E/PE) equipment. This standard was developed in the mid-1980s and has been revised several times to cover the technical advances in various industries. In addition, derivative standards have been developed for specific markets and applications that prescribe the particular requirements on functional safety systems in these industry applications. Example applications include process automation (IEC 61511), machine automation (IEC 62061), transportation (railway EN 50128), medical (IEC 62304), automotive (ISO 26262), power generation, distribution, and transportation. 图Figure 1. local Safety System

The Virtex-4 features, such as the programmable IDELAY and built-in FIFO support, simplifythe bridging of a high-speed, PCI-X core to large amounts of DDR-SDRAM memory. Onechallenge is meeting the PCI-X target initial latency specification. PCI-X Protocol Addendum tothe PCI local Bus Specification Revision 2.0a ([Ref 6]) dictates that when a target signals adata transfer, "the target must do so within 16 clocks of the assertion of FRAME#." PCItermination transactions, such as Split Response/Complete, are commonly used to meet thelatency specifications. This method adds complexity to the design, as well as additional systemlatency. Another solution is to increase the ratio of the memory frequency to the PCI-X busfrequency. However, this solution increases the required power and clock resource usage.

一、安装SQL数据库 1、 打开Microsoft SQL Server 企业管理器 2、 建立一个新的数据库，名称为 XfokSite_Free (必须为这个名字) 3、选择该数据库，点击鼠标右键 -> 所有任务 -> 还原数据库 -> 从设备 -> 选择设备 -> 添加 -> 选择程序目录下的数据库里面的文件 二、安装程序 1、如果程序没有放在虚拟目录下，请把所有文件放在网站根目录下，否则会提示出错。 三、设置 1、 用文本编辑器打开web.config 2、 找到<add key="SqlConnectionString" value="Data Source=(local) Integrated Security=false Initial Catalog=XfokSite_Free User ID=xfok Password=xfok" /> 红色部分：数据库服务器地址，如果为本地地址，请设置为(local)，外部请直接修改为IP地址（不要加括号） 深红部分：数据库名称 粉红部分：SQL数据库登陆用户名 蓝色部分：SQL数据库登陆密码 四、设置完毕！ 直接在浏览器中敲入地址，来体验一下心随我动，网站建设超轻松的快感吧！

刚刚学习jdbc数据库，用jcreator编了一个小数据库，还可以，通过了。 功能：能够进行添加数据、修改数据、查找数据、删除数据、还可以上下翻页！ 注： 里面的东西还没有进行整理，多少还有一些凌乱。由于刚刚学，有些功能不知道，许多功能还是按照以前的知识进行写的，多少显得笨拙！但也是一种解决的方法，可供初学者 参考。 说明文档－－给初学者 1、首先把数据库文件加入到SQLSERVER数据库中DATA路径下， 2、在SQL SERVER中：右键选中数据库/所有任务/附加数据库/找到需要附加数据库的路径 注意在这一步中，应该都是对号，否则就要检查是否文件名一致的问题 3、在管理工具/ODBC数据源管理器/系统DSN/添加SQLSERVER数据源/ 记住：在这一步中数据源起名是OO,本机服务器是(local)，要更改默认的数据库为clientregister.

是用jbuilder9做的一个简单程序。单窗体，有添加删除查询更新几个功能，用的是SQL Server数据库。服务器名local 用户名sa 密码hunterd.（不要忘了改数据源和导入数据） 第一次用java 和jbuilder编程，可能还有些问题吧。
