Since the technology of serial interface and parallel interface appeared in 1980 , universal serial bus of intel has become the most important standard of computer peripheral component interconnect 通用串行总线usb是自1980年串口和并口技术出现以来，最重要的计算机外设互联标准之一。
Pci ( peripheral component interconnect ) bus , which has been the first chosen in recent years for pc local bus because of its high performance , is an excellent bus for multimedia Pci ( peripheralcomponentinterconnect )总线是近年来出现的一个面向多媒体技术的优秀总线，它凭借许多高端性能而成为pc机局部总线的首选。
Pci ( peripheral component interconnect ) local bus is one of the high performance computer system local bus being used broadly today . it ’ s interface has become the very important circuit module of most computer systems Pci ( peripheralcomponentinterconnect )总线是一种高性能,广泛使用的计算机局部总线,其接口电路已经成为各种计算机系统很重要的功能模块电路。
From the emergence of pci ( peripheral component interconnect ) in 1993 , pci has been widely adopted as a high performance bus protocol and used in various systems ranging from portable computer to supercomputer 自1993年pci ( peripheralcomponentinterconnect ，外部设备互联)总线标准建立， pci已经成为一种被广泛采用的总线结构，应用于从便携式电脑到大型服务器等多种计算机系统中。
Because the software for protection is mainly used in a real - time checking subsystem in an industry system , and needs faster speed of data transport , so the pci ( peripheral component interconnect ) interface criterion is utilized in the software protection card 由于所研究的软件保护技术主要是用来保护工业实时检测软件，要求有较快的数据传输速度，所以采用pci接口的软件保护卡来实现。
This thesis designes a motion control board which is based on dsp ( digital signal processor ) , the aspects including high speed and high precision , real - time response and opening design of hardware are considered in the design . the motion control board can be plugged in the pci ( peripheral component interconnect ) slot of pc ( personal computer ) , thus forms an inboard open cnc system 本文从高速高精度、实时性和硬件开放式设计等方面考虑,设计了一款基于dsp ( digitalsignalprocessor )的运动控制卡,该卡可直接插接在pc ( personalcomputer )机的pci ( peripheralcomponentinterconnect )插槽中,和pc机组成pc内藏cnc ( computernumericalcontrol )型开放式数控系统。
At first , it discusses the way to design a data acquisition and storage system with high speed based on pci ( peripheral component interconnect ) bus , then the author implements the device driver to acquisition the image data with high speed in real time in the kernel mode of system based on researching deeply of the mechanism and structure of kernel mode in windows operating system 首先讨论了pci （ peripheralcomponentinterconnect ? ?外围部件互连）总线高速多通道数据采集与存储系统硬件接口设计方法，然后深入讨论了基于windows系统核心态结构机制基础上的设备驱动程序的设计方法，最后讨论了cd - 650bx的设计与实现。
