  • 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

    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

  • 朴素贝叶斯(Naive Bayes, NB)算法是机器学习领域中常用的一种基于概率的分类算法

    朴素贝叶斯(Naive Bayes, NB)算法是机器学习领域中常用的一种基于概率的分类算法,非常简单有效。k近邻法(k-Nearest Neighbor, kNN)[30,31]又称为基于实例(Example-based, Instance-bases)的算法,其基本思想相当直观:Rocchio法来源于信息检索系统,后来最早由Hull在1994年应用于分类[74],从那以后,Rocchio方法就在文本分类中广泛应用起来。

  • function [U,V,num_it]=fcm(U0,X) % MATLAB (Version 4.1) Source Code (Routine fcm was written by R

    function [U,V,num_it]=fcm(U0,X) % MATLAB (Version 4.1) Source Code (Routine fcm was written by Richard J. % Hathaway on June 21, 1994.) The fuzzification constant % m = 2, and the stopping criterion for successive partitions is epsilon =??????. %*******Modified 9/15/04 to have epsilon = 0.00001 and fix univariate bug******** % Purpose:The function fcm attempts to find a useful clustering of the % objects represented by the object data in X using the initial partition in U0.

  • CF卡(Compact Flash)最初是一种用于便携式电子设备的数据存储设备。作为一种存储设备

    CF卡(Compact Flash)最初是一种用于便携式电子设备的数据存储设备。作为一种存储设备,它革命性的使用了闪存,于1994年首次由SanDisk公司生产并制定了相关规范。当前,它的物理格式已经被多种设备所采用。从外形上CF卡可以分为两种:CF I型卡以及稍厚一些的CF II型卡。从速度上它可以分为CF卡、高速CF卡(CF+/CF 2.0规范),更快速的CF 3.0标准也即将在2005年被采用。CF II型卡槽主要用于微型硬盘等一些其它的设备

  • MPI stands for the Message Passing Interface. Written by the MPI Forum (a large committee comprising

    MPI stands for the Message Passing Interface. Written by the MPI Forum (a large committee comprising of a cross-section between industry and research representatives), MPI is a standardized API typically used for parallel and/or distributed computing. The MPI standard is comprised of 2 documents: MPI-1 (published in 1994) and MPI-2 (published in 1996). MPI-2 is, for the most part, additions and extensions to the original MPI-1 specification. The MPI-1 and MPI-2 documents can be downloaded from the official MPI Forum web site: http://www.mpi-forum.org/. Open MPI is an open source, freely available implementation of both the MPI-1 and MPI-2 documents. The Open MPI software achieves high performance the Open MPI project is quite receptive to community input.

  • Like many of my colleagues in this industry, I learned Windows programming from Charles Petzold s Pr

    Like many of my colleagues in this industry, I learned Windows programming from Charles Petzold s Programming Windows—a classic programming text that is the bible to an entire generation of Windows programmers. When I set out to become an MFC programmer in 1994, I went shopping for an MFC equivalent to Programming Windows. After searching in vain for such a book and spending a year learning MFC the old-fashioned way, I decided to write one myself. It s the book you hold in your hands. And it s the book I would like to have had when I was learning to program Windows the MFC way.

  • Supplemental information for a high-speed serial bus that integrates well with most IEEE standard 3

    Supplemental information for a high-speed serial bus that integrates well with most IEEE standard 32-bit and 64-bit parallel buses is specified. It is intended to extend the usefulness of a low-cost interconnect between external peripherals, IEEE Std 1394-1995. This standard follows the ISO/IEC 13213:1994 Command and Status Register (CSR) architecture.

  • 关于JTAG的介绍

    百度关于JTAG接口的介绍。JTAG是英文“Joint Test Action Group的词头字母的简写,该组织成立于1985 年,是由几家主要的电子制造商发起制订的PCB 和IC 测试标准。JTAG 建议于1990 年被IEEE 批准为IEEE1149.1-1990 测试访问端口和边界扫描结构标准。该标准规定了进行边界扫描所需要的硬件和软件。自从1990 年批准后,IEEE 分别于1993 年和1995 年对该标准作了补充,形成了现在使用的IEEE1149.1a-1993 和IEEE1149.1b-1994。JTAG 主要应用于:电路的边界扫描测试和可编程芯片的在系统编程。
