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

一、 使用键盘显示接口芯片8279接收按键键值，并在七段数码管上显示出来，通过判断键值进入相应音乐播放处理程序。在音乐播放程序中，使用定时器/计数器8253的计数器2，使其工作在方式¬ ¬ 3―方波发生器，通过查表依次取出乐曲频率值送入计数器作为计数初值，经out2输出方波，驱动扬声器发出不同频率的声音，在每个音阶之间加入相应的延迟时间，即实现了音乐的播放。-First, the use of a keyboard display interface chip receive keys keys 8279, and Seven-Segment LED display, through to determine the corresponding music player keys to enter the treatment program. Procedures in the music player, use the timer/counter 2 counter 8253 to work in the way ? ? 3- square-wave generator, followed by out music through the look-up table values into the counter as a frequency count of the initial value, the output side out2 waves, driven loudspeakers of different frequency sound, in between each scale by adding the appropriate delay time, namely, the realization of the music player.
