<table id="gk2k2"></table> This document provides practical, common guidelines for incorporating PCI Express interconnect layouts onto Printed Circuit Boards (PCB) ranging from 4-layer desktop baseboard designs to 10- layer or more server baseboard designs. Guidelines and constraints in this document are intended for use on both baseboard and add-in card PCB designs. This includes interconnects between PCI Express devices located on the same baseboard (chip-to-chip routing) and interconnects between a PCI Express device located “down” on the baseboard and a device located “up” on an add-in card attached through a connector. This document is intended to cover all major components of the physical interconnect including design guidelines for the PCB traces, vias and AC coupling capacitors, as well as add-in card edge-finger and connector considerations. The intent of the guidelines and examples is to help ensure that good high-speed signal design practices are used and that the timing/jitter and loss/attenuation budgets can also be met from end-to-end across the PCI Express interconnect. However, while general physical guidelines and suggestions are given, they may not necessarily guarantee adequate performance of the interconnect for all layouts and implementations. Therefore, designers should consider modeling and simulation of the interconnect in order to ensure compliance to all applicable specifications. The document is composed of two main sections. The first section provides an overview of general topology and interconnect guidelines. The second section concentrates on physical layout constraints where bulleted items at the beginning of a topic highlight important constraints, while the narrative that follows offers additional insight.

total是最后的版本。包括的全是最新的物理層和數據鏈路層。另外還有pro1和pro2的打包程序和調用它們形成的各自的界面程序，以及最后調用各個界面形成的總界面程序。由于時間匆忙，對數據鏈路層協議的界面化工作只做到了pro2，總界面上已經留了所有6個程序的地方。PhysicalLayer包中包含了所有的物理層的程序的版本，以及它們各自的演示程序(一般為Physical)及打包程序(一般為PhyLayer)。顯示了整個物理層編寫及修改演化的過程，僅供參考。Datalink Layer包中包含了數據鏈路層程序的各個版本。包含數據鏈路層基本操作模塊(Datalink.java)及各個協議的版本(pro1-pro3)。以及它們各自的演示程序及打包程序。顯示了整個物理層編寫及修改演化的過程，僅供參考。運行方法：只需要Java的運行環境。先要預裝java，這里使用的是java的j2sdk-1_4_2_01-windows-i586版本。最新的1.5.0應該也支持。采用的編譯器是Jcreator，其他的編譯器也應該是可以用的。

This toolbox distributes processes over matlab workers available over the intranet/internet (SPMD or MPMD parallel model). It is very useful for corsely granular parallelization problems and in the precesence of a distributed and heterogeneus computer enviroment. No need for configuration files ! Cross platforms, cross OS and cross MATLAB versions. Workers can be added to the parallel computation even if it has started. No need of a common file system, all comms are using tcpip connections

This Delphi 4.0 example uses the MapX Ver 4.0 OCX Control. The main goal of this example is to show the use of the new object editing capabilities in MapX Ver 3.51. The program show how to perform functions such as adding a new layer adding lines and points, and editing a layers data.

Windows XP集成了許多功能和服務，但是有很多服務是我們個人用戶所用不到的，開啟只會浪費內存和資源，而且，還影響激活速度。比如alerter、application layer gateway service、application management等等。

Base64 demonstrates how easy it is to decipher plaintext usernames and passwords. Never login to a public network resource unless some type of encryption is being used, secure socket layer is one example. Most FTP sites also use plaintext passwords.
