This text describes the basie train of thought and the basie method of the reform of the computer hardware teaching of computer science and technology speciality in Chinese normai universities from the angle of the social develop-ment in the 21 st century.

1引言 计算机系统是由硬件系统和软件系统构成的，硬件系统和软件系统既相对独立又相互作用，相辅相成，构成一个完整的系统，并且缺一不可。

The paper defines some command codings which are used to make communication between the system and a computer and it also describes how to construct a system based on the PIC MCU , design the application software and drive software for hardware.

使用 PIC 芯片实现系统的硬件构架，定义了计算机与系统之间进行通信使用的命令编码，设计了系统应用软件和硬件接口驱动程序。

At the same time, with the progresses of computer, especially with the applications of DSP, the har

与此同时，计算机技术的进步，特别是高性能DSP 芯片的出现和应用，使得微机保护硬件平台资源更丰富，计算速度更快，为保护的功能完善提供了良好的硬件支持。

The experiment system is made up of control object, test instrument, connection board, date gather card and computer. The experiment system software based on LabVIEW7.0 and PCL -818L is devoleped.

在该系统硬件构成中，采用加热炉作为控制对象，试验仪器，线路板，数据采集卡及PC机，实现了对计算机控制技术的实践教学系统的硬件环境配置。

This paper introduced an application of IEEE-488 interface card for PCHardware and software were simple and practical.

本文介绍了一种计算机用IEEE-488接口卡的硬件和软件设计。硬件主要采用一块8255芯片，软件使用C语言。

The measured object can be found within a few milliseconds in the raster-scan image. 4 . Two lines delay for the processed image is implemented using two 128×8 shift registers with the configurable logic block in FPGA. A new fully pipelined bit parallel hardware architecture for Sobel edge detection is implemented with FPGA. Furthermore, it takes no more than 2ms to complete the edge detection of an image with 128×128 pixels.

视觉检测信号的前端处理技术 1、系统地分析了视觉检测算法层次性特点和计算特点，提出了提高视觉检测信号处理速度的基本方案：采用前端处理系统，自动识别被测物体在获取图像中的位置，并将真正有用的被测物体的边缘坐标值，提供给计算机，作进一步的高精度处理； 2、系统研究了实时图像硬件处理的设计基本方法，提出了基于FPGA的视觉检测信号的低级处理算法硬件实现模块化模型； 3、提出了一种新的基于FPGA的模板匹配并行模块化结构，解决了二维图像处理高带宽要求，在几毫秒内就可以在按扫描顺序输入图像中找到检测目标物体的位置； 4、采用FPGA内部的可配置逻辑块实现了128×8移位寄存器的设计，解决了大容量移位寄存器与FPGA内部寄存器数量之间的矛盾，实现了两行图像的延迟。

On PC-compatible computers, the set of essential software routines that tests hardware at startup,starts the operating system, and supports the transfer of data among hardware devices.

在PC兼容计算机上的一组基本软件例程，这些程序在计算机开机时测试硬件，启动操作系统，支持硬件设备之间的数据传输。

In the last few years, along with the computer hardware and the software technology unceasing development and the computer popularization, the computer servosystem (Computer-Aided Design) the technology also obtained the enormous development.

近几年来，随着计算机硬件和软件技术的不断发展和计算机的普及，计算机辅助系统（Computer-Aided Design）技术也得到了极大发展。

Therefore, it is necessary for modern enterprises to supply reliable and real-time information and services by utilizing computer systems, more and more departments especially those pivotal departments have been unprecedentedly relied on computer systems, however, it is unavoidable for the hardware and software of a computer to have a breakdown, which may certainly results in unmeasured losses.

对现代企业来说，利用计算机系统来提供及时可靠的信息和服务是必不可少的，越来越多的行业、部门，尤其是关键部门，对计算机系统呈现出前所未有的依赖性。但是计算机的硬件和软件都不可避免地会发生故障，会带来无可估量的损失。

In their over 20 years' development process, the printer channels have experienced a process from big profit to low, low sales to huge, low cost to high, simple distribution sales to the specialized sales.

上世纪40年代，计算机技术产生并应用于超级计算中，随着计算技术和计算机硬件技术的不断发展，计算机不断应用在办公、家庭等领域。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
