一些基本的浮点数运算实现,可以方面地在ASM环境下调用这些子程序,简化编程-Some of the basic floating-point realize, you can easily call in ASM environment of these subroutines, simplify programming

此系统是本人做毕业设计时候的老东西了，是汇编写的。可以在PROTEUS上仿真，实际效果和仿真效果一模一样，电梯的功能相信大家都很了解，我就不在这多讲了。但要说明的一点是：我这个系统是仿真用的，有些东西不能和现实中的电梯相比，里面可能有某些方面考虑的不是很周到，希望有心的朋友提点意见，谢谢我的E-MAIL:qq317999920@163.com-This system is designed when I graduated to do the old things is a compilation of writing. Be able to PROTEUS on the simulation, the actual results and simulation of the effect of exactly the same as the functions of elevator think we all understand that I am not in this more than a speech. But the point is to explain: I used this system is the simulation of, some things can not be compared to the reality of the elevator, which may have to consider certain aspects of the not very thoughtful, I hope interested提点意见Friend, thank you my E-MAIL: qq317999920@163.com

目前已有若干版本的子程序库公开发表，它们各有特色。本程序库中的开平方算法为快速逼 近算法，它能达到牛顿迭代法同样的精度，而速度加快二十倍左右，超过双字节定点除法的 速度。 本子程序库对《单片机应用程序设计技术》一书附录中的子程序库作了重大修订： （１）按当前流行的以 IBM PC 为主机的开发系统对汇编语言的规定，读者不必再进行修 改，便可直接使用。 （２）对浮点运算子程序库进行了进一步的测试和优化，对十进制浮点数和二进制浮点数的 相互转换子程序进行了彻底改写，提高了运算精度和可靠性。 （３）新增添了若干个浮点子程序（传送、比较、清零、判零等），使编写数据处理程序的 工作变得更简单直观。 在使用说明中开列了最主要的几项：标号、入口条件、出口信息、影响资源、堆栈需求，各 项目的意义请参阅《单片机应用程序设计技术》第六章 6.3.7 节的内容。程序清单中开列 了四个栏目：标号、指令、操作数、注释。为方便读者理解，注释尽力详细。 -err

运行可执行程序testword.exe，出现菜单主界面，按回车键出现由26个字母组成 的乱序行，这时其中任一字母落下，在键盘上敲入该字母，如果输入正确，字母 消失；按ESC键返回主界面；按空格见暂停；按‘E’退出。-running executable testword.exe, appeared main menu interface, press the Enter key emerging from the 26 letters of disorder OK, then any one of the letters ended in Jianpanshangqiao into the letters, If the input is correct, the letters disappeared. by the ESC key to return to the main interface; see box by the moratorium; by the "E" withdrawal.

用vc写的外壳 通过调用asm生成的程序来读出或写入cmos。解释CMOS每一字节含义.- The outer covering writes which with vc through transfers the asm production the procedure to read out or to read in cmos. Explains the CMOS each byte meaning

This a program that I wrote many years ago. It is a floppy disk , disk copy,disk info,and format program. All written in masm assembler. There is also a small 252 byte driver that allows nonstandard floppy formats on dos systems below 7.0. Floppies can be formatted in any track and sector layout. 1.44M floppies can be formatted to 1.76 M. All source code,includes and libraries are included. Modify the bld.bat file to your own needs. There are many asm tricks in the source code. Have fun with this old code.-This is a program that I wrote many years ago. It is a floppy disk , disk copy,disk info,and format program.
