  • pci e PCB设计规范

    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.

    This simple SDI Notepad-like application demonstrates how, taking advantage of the MFC support for Unicode, to Turkmenize labels of the specified menu Items. Actually, Turkmen is not supported by Windows 2000, therefore, to create such resources as menu so that strings in Turkmen could be displayed I had to invent an additional technique 这是一个与记事本类似的简单的SDI应用程序,演示了怎样使用MFC来支持 Unicode,对指定的菜单条目进行Turkmenize标签化。实际上,Windwos 2000并不支持Turknen,因此,创建了那些菜单资源以便那些字符串可以在Turknen中显示,为此我必须开发其它的技术。 来源: http://www.codeguru.com/advancedui/SDI_Note.html

    The project Adventure is a simple text-based adventure game. The game, as given, involves the hero trying to find his way from a deep dark forest to home and his true love. There s very little else the player can do apart from moving from place to place. It s not really very interesting. This project can be of use beyond the given, rather boring forest adventure though. You can use it as a basis for developing your own adventure game with different, more interesting commands, areas, Items, people and so on. The package ope.adventure contains classes to describe the game world.

    Atheros无线芯片AR-6000系列wince 6驱动源代码(这东西我也没用过别问我,我是搜别的wince资源搜到的) AR6K SDIO support. Requires firmware 1.1 on SD13 cards. readme: Atheros Communications AR6001 WLAN Driver for SDIO installation Read Me March 26,2007 (based on k14 fw1.1) Windows CE Embedded CE 6.0 driver installation. 1. Unzip the installation file onto your system (called installation directory below) 2. Create an OS design or open an existing OS design in Platform Builder 6.0. a. The OS must support the SD bus driver and have an SD Host Controller driver (add these from Catalog Items). b. Run image size should be set to allow greater than 32MB. 3. a. From the Project menu select Add Existing Subproject... b. select AR6K_DRV.pbxml c. select open This should create a subproject within your OS Design project for the AR6K_DRV driver. 4. Build the solution. 转自Tony嵌入式,原文地址:http://www.cevx.com/bbs/dispbbs.asp?boardID=4&ID=11762&page=1

  • IDE开发环境

    IDE开发环境,可以挂载SDCC The BASIC IDE is a new, RAD (Rapid Application Development) IDE (Integrated Development Environment) for the RapidQ programming language. The IDE currently has rich project options, a form designer (similar to Delphi s), and code editor. The BASIC IDE is being coded in Borland® Delphi® . We are currently using Delphi 6, but you should be able to use Delphi 3 or later (Delphi 7 included). Some of the BASIC IDEs features include: Form Designer with support for all of RapidQ s components Flexible Code Editor Project Management Written in OO (Object Oriented) Delphi. Some future Items that we are working on are: Code Tip Code Completion CVS Integration Code Editor Macros Point-and-Click access to subroutines, functions, and variables
