显示80X86的寄存器-show 80X86 register

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.

这是一个包含了基本操作的记事本软件，与Windows下的记事本软件相似。其中包含了所有的源代码。-This is a notebook that contains the basic operation of the software, and Windows, the software similar to Notepad. Which contains all the source code.

本软件实现了汇编语言级虚拟机的模拟，可以当作一个简易的汇编工具使用，同时又演示了CPU的工作过程，对于学习计算机组成原理和汇编语言是有一定帮助的-the assembly language level virtual machine simulation and can be used as a simple compilation of the use of tools, but also demonstrated the CPU process, learning theory and computer component assembly language is a definite help in the

电视遥控器软解码程序-TV remote control procedures

本书以X86系列微机为背景，从简单的Hello程序开始，系统而详细地阐述了X86微机汇编语言编程的各种基础知识和编程技巧，内容涉及到数据表示、存储器管理、各种数据类型、过程、与汇编语言相关的体系结构、控制结构、文件、宏指令、位处理指令、字符串指令、MMX指令、类和对象，以及混合语言编程等，尤其是在高级汇编语言（HLA）方面，该书给予了细致深入的讲解。对于有意学习X86汇编语言编程的程序员来说，这是一本难得的好书。 本书的作者Randall Hyde在大学中教授汇编语言十多年，并且开发了好几个商用软件，具有丰富的汇编语言开发经验。该书的英文电子版受到了成千上万的网站和高级程序员的高度评价，已经成为了高级汇编语言编程方面的一本经典之作。虽然该书的出版时间不长，但在Amazon上为该书作出评价的人很多，而且几乎所有的人都给予5星的评价，可见其内容之好。笔者相信，随着时间的推移，它在程序员中的影响回越来越大-this book X86 computer as a background, from a simple Hello proceedings began, and the system described in detail in the X86 PC assembly language programming in basic knowledge and programming skills, which relates to the data, memory management, data types, processes, and assembly language related to the body the grade structure, the control structure, document, macros, handle the orders, string instructions MMX instructions, classes and objects, as well as mixed-language programming, particularly at the senior assembly language (HLA), the book to give a detailed in-depth explanations.
