Description: 2001年春季的IDF上Intel正式公布PCI Express，是取代PCI总线的第三代I\O技术，也称为3GIO。该总线的规范由Intel支持的AWG（Arapahoe Working Group）负责制定。2002 年4月17日，AWG正式宣布3GIO 1.0规范草稿制定完毕，并移交PCI-SIG进行审核。开始的时候大家都以为它会被命名为Serial PCI（受到串行ATA的影响），但最后却被正式命名为PCI Express。2006年正式推出Spec2.0（2.0规范）-err

Description: 【下载说明】
这里提供给大家的是《Embedded Linux: Hardware, Software, and Interfacing》（嵌入式 Linux---硬件、软件与接口）一书的英文原版CHM格式下载。
【作者简介】
Craig Hollabaugh has been fascinated by electronics since he bought an AM radio in elementary school. He was first exposed to Unix during a cross-country talk session in 1985. Later, he administered networked Sun and DEC workstations while pursuing a doctoral degree in electrical engineering at Georgia Institute of Technology.
【内容提要】
本书通过一个冬季旅游胜地自动化管理项目实例，从软件、硬件和接口的观点介绍嵌入式Linux。引入项目需求后，作者讲述了开发环境的建立，接着用一系列软硬件接口实例展示了如何使用异步串行通信、PC并口、USB、内存I/O、同步串行通信以及中断，等等。最后介绍了将前面所有的工作有机地组织在一起的系统集成过程。本书以实际应用为导向，书中整个项目的实施过程和软硬件接口实例都具实践指导意义。-err

Description: 一个单片机应用系统的硬件电路设计包含两部分内容：一是系统扩展，即单片机内部的功能单元，如ROM、RAM、I/O、定时器/计数器、中断系统等不能满足应用系统的要求时，必须在片外进行扩展，选择适当的芯片，设计相应的电路。二是系统的配置，即按照系统功能要求配置外围设备，如键盘、显示器、打印机、A/D、D/A转换器等，要设计合适的接口电路。-Application of a single-chip hardware circuit design contains two parts: First, expanding the system, that is, single-chip s internal functional unit, such as ROM, RAM, I/O, timer/counter, interrupt system can not meet the application system the request must be expanded in the chip, select the appropriate chips, the design of the corresponding circuit. Second, the system configuration, that is the functional requirements in accordance with the system configuration peripherals such as keyboards, monitors, printers, A/D, D/A converters and so on, to design an appropriate interface circuit.

Description: The PCI Local bus concept was developed to break
the PC data I/O bottleneck and clearly opens the door
to increasing system speed and expansion capabilities.
The PCI Local bus moves high speed peripherals
from the I/O bus and places them closer to the system’s
processor bus, providing faster data transfers
between the processor and peripherals. The PCI Local
bus also addresses the industry’s need for a bus standard
which is not directly dependent on the speed,
size and type of system processor. It represents the
first microprocessor independent bus offering performance
more than adequate for the most demanding
applications such as full-motion video.-The PCI Local bus concept was developed to breakthe PC data I/O bottleneck and clearly opens the doorto increasing system speed and expansion capabilities.The PCI Local bus moves high speed peripheralsfrom the I/O bus and places them closer to the system sprocessor bus, providing faster data transfersbetween the processor and peripherals.
