A topdown design of an 8bit RISC MCU is presented, in order to overcome the limitation of MCS51 microcontroller The core is based on Harvard architecture with 16bit instruction length and 8bit data length The performance of the MCU has been greatly improved by introducing singleclockcycle instructions, setting multiple highspeed working registers, replacing microprogram with direct logic block, etc FPGA verification and computer simulation show that its maximum clock frequency and instruction e...

在对传统的MCS51系列单片微控制器的局限性进行分析的基础上，设计了一种基于增强8位RISC构架的微控制器内核。该MCU核采用哈佛结构、16位指令字长和8位数据字长，通过设计单周期指令、在内部设置多个快速寄存器及采用硬布线逻辑代替微程序控制的方法，加快了微处理器的速度，提高了指令的执行效率。计算机仿真验证和FPGA仿真验证的结果表明，该MCU的最高时钟频率和指令执行效率等指标均优于MCS51的5倍以上。

This design mainly and the computer applies the programmable controller in elevator's control system, as regularly completes the single Taiwan elevator PLC control system's overall project design, the composition and the modularized program design take five elevators.

The paper's aim.By designing the 32bit application program that runs on the 32bit operating system of Window 98/2000/XP with Visual C++ language the paper makes the computing of the time sequence of those displacements and prediction on Bai-yun-e-bo east mine roboticized, to input the coordinate data, choice the parameterchoice menus and click the button need be done by those extended technology personnel, then forecasting the slope's Stability will be accomplished, it make those extended technology personnel free from calculating onerously , then them will devote their mind to study the theoretics.

本论文通过用美国微软公司著名的应用程序开发工具—Visual C++ 6.0编制了运行在Windows 98/2000/XP等操作系统下具有微软Internet Explorer 6.0 风格的32位应用程序，使对白云鄂博铁矿东矿边坡位移值的时间序列的计算和预测全部由计算机自动完成，一般技术人员所要做的仅仅是输入测点的空间坐标数据和预测所需要的一些参数，通过选择菜单选项和单击按钮，就能实现对白云鄂博铁矿东矿边坡失稳的预测，从而使广大技术人员从繁重的计算中解放出来，把精力放在具体的理论研究中。

All he knows is that he decided not to print the document before the first page appeared in the printer's output basket, he clicked the Cancel button, and then the stupid application continued printing for 15 pages even though he acted in plenty of time to stop it.

他所知道的是，在打印机输出栏中出现第1页纸之前已经决定不打印文档。他单击了取消按钮，然后愚蠢的程序继续打印了15页。尽管他有足够的时间来终止它，程序甚至接受了用户的取消命令。

As an illustration, a single-item single-criteria procurement auction under proposed mechanism is addressed detailedly on bidding process and both-side players\ strategies, including suppliers\ optimal bidding, procurer\s bid evaluation, winner determination, rebidding suggestion construction and so on.

在密封式循环拍卖机制的基础上，本文继而针对单物品单属性采购详细设计和讨论了拍卖双方的行为策略，包括供应商的最优投标策略，采购商的投标评估过程，优胜者选择程序和再投标建议构造等。

This feature would be quite useful in most programs, too, whether spreadsheet, drawing program, or invoice generator.

数据无论如何应该保留在缓冲区中，这种特性对于很多程序非常有用，无论是电子表单、绘图程序，还是发票制作软件。

Analyse the technology principle of program tracking, step-in tracking, conical scan tracking and singleshot tracking, and contrast the advantage and disadvantage of them. Select program tracking and conical scan tracking considering performance and cost.

二、对程序跟踪、步进跟踪、圆锥扫描跟踪和单脉冲跟踪这四种自动跟踪技术的原理进行了具体的分析，并比较了它们各自的优缺点，从性价比的角度，选择了程序跟踪与圆锥扫描跟踪相结合的方式。

In the chapter 4, some mathematic modules are constructed , which are rules of the system programs, we use second-grade parameters to identify input signals. Based on mathematic modules and second-grade parameters, system programs using "Top-Down" designing idea are divided into some module programs in the chapter 5, At the end of this chapter, questions and resolutions in testing are introduced; In the last chapter .application of download characteristics of MCU is used on long distance update , so the totalizer can be used in broad fields if software designed reasonably .

第四章中先介绍了程序中使用的一些数学模型和利用设置二级参数确定输入信号类型的方法；第五章中介绍了采用自顶向下的模块划分程序设计方法编制的系统软件的过程，并在章末介绍了系统调试方面出现的问题和相应的解决方案；第六章利用MCU的下载特性和网络功能，推出实现智能仪表软件的远程升级方案，通过软件设计，使得仪表有了更为广泛的应用空间，实现单表多用。
