通用串行总线(USB)是一种新兴的计算机外围串行通信接口标准，与常用的计算机接口(如串口、并口等)相比，通用串行总线(Universal Serial Bus，USB)具有热插拔、即插即用、数据传输可靠、扩展方便、低成本等优点。从问世以来，它得到了广泛的应用，一方面已成为当前计算机必备的接口之一，同时也被广泛地应用于嵌入式系统设计中。 从1994年USB 0．7出现开始，USB实施者论坛(Implementation Forum)先后定义了USB 0．8、0．9、1．0、1．1、2．0以及USB OTG等规范，以及各种不同的设备类规范。其中USB1．1规范目前正逐步广泛应用，而USB2．0和USBOTG作为USB协议的更新和扩展，也将使USB占领更广的外设

NAME Control_AT24Cxx This collection of routines allows an AT89C2051 microcontroller to read and write the AT24Cxx family of serial CMOS EEPROMS. This version of the code is compatible only with the AT89C2051 due to the location of the data buffer and stack in RAM. The code may be modified to work with the AT89C1051 by relocating or resizing the buffer and stack to fit into the smaller amount of RAM available in the AT89C1051. Note that the minimum size of the buffer is determined by the page size of the AT24Cxx.

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）

Eckel’s book is the only one to so clearly explain how to rethink program construction for object orientation. That the book is also an excellent tutorial on the ins and outs of C++ is an added bonus

n this demo, we show how to use Rao-Blackwellised particle filtering to exploit the conditional independence structure of a simple DBN. The derivation and details are presented in A Simple Tutorial on Rao-Blackwellised Particle Filtering for Dynamic Bayesian Networks. This detailed discussion of the ABC network should complement the UAI2000 paper by Arnaud Doucet, Nando de Freitas, Kevin Murphy and Stuart Russell. After downloading the file, type "tar -xf demorbpfdbn.tar" to uncompress it. This creates the directory webalgorithm containing the required m files. Go to this directory, load matlab5 and type "dbnrbpf" for the demo.
