4． 程序设计内容
（1． 在设计过程中我们用一个存储单元作为秒计数单元，当一秒钟到来时，就让秒计数单元加1，当秒计数达到60时，就自动返回到0，从新秒计数。
（2． 对于秒计数单元中的数据要把它十位数和个数分开，方法仍采用对10整除和对10求余。
（3． 在数码上显示，仍通过查表的方式完成。
（4． 一秒时间的产生在这里我们采用软件精确延时的方法来完成，经过精确计算得到1秒时间为1.002秒。

MS2 程序分析

一：下载MS2.RAR 压缩包解压缩后可以看到如下界面：
第一项为MS2 软件包，第二项为SourceInsight3.0，它是一款非常优秀的C 语言编辑器，目
前各个大公司，比如华为等都用它，手机行业几乎无一例外。它的作用是代替Keil 的编辑
环境，因为Keil 的编辑环境太难看了，并且使用也不方便，用它来看程序，查找函数特别
容易，以下是它的界面：
各位可以看到，它里面不同的关键字的颜色都是不同的，看上去很舒服，最主要的还是它的
查找功能，比如要看MSTimerStart 的函数原型，但不知道他在那个地方，双击函数名，右
击后出现属性，点“Jump to Definition”，就可以看到函数原型，这个功能Keil 下也有，还
有一个Keil 下没有的，就是这个函数被谁调用了，双击函数名，右击后出现属性，点“Jump
to Caller”。
具体请参考SourceInsight 使用说明，也就是第四项，第三项是周立功的DP-51 电路图,因为
MS2 的设计本身是不倚赖外设的，所以没有加外部接口，直接用串口来演示，如下图：
大家可以看到liweifeng， test1，test2，test3 在不停的打印，这是四个伪任务，按一定的时
候间隔打印，我们将在后面分析。当然按键等都可以在处理字符串栏中输入，在接收窗口显

按键扫描 51单片机加8279
8279通过74LS 138译码器扩展4×4键盘、6位显示器。
由3-8译码器对SL0～SL2译出键扫描线，由另一3-8译码器译出显示器的位扫描线，并采用了编码扫描方式。
为了防止出现重键现象，扫描输出线高位SL3不参加键扫描译码。CPU对8279的监视采用了查询方式，故8279的中断请求信号IRQ悬空未用。

关于匈牙利命名法的说明
有关匈牙利命名法的一点有意思的说明是它的名字的由来。这种命名技术是由一位能干的 Microsoft 程序员查尔斯·西蒙尼(Charles Simonyi) 提出的，他出生在匈牙利。在 Microsoft 公司中和他一起工作的人被教会使用这种约定。这对他们来说一切都很正常。但对那些 Simonyi 领导的项目组之外的人来说却感到很奇特，他们认为这是死板的表达方式，甚至说代有这样奇怪的外观是因为它是用匈牙利文写的。从此这种命名方式就被叫做匈牙利命名法。
On the nomenclature of Hungary Hungary nomenclature on the interesting point that it is the origin of its name. This technology is named by a competent Microsoft programmer Charles Simonyi (Charles Simonyi) proposed, he was born in Hungary. In Microsoft and his company were working with the Church the use of such an agreement. To him, that everything is normal. But for those who Simonyi led the project team beyond those who find it very strange that they think this is the rigid way of expression, and even that generation has such a strange appearance because it is written in Hungarian. Since then this naming has been called the Hungarian nomenclature. (2007-07-27, Visual C++, 10KB, 下载41次)
设计一个按时间片轮转法实现处理器调度的程序
[提示]：
（1）假定系统有5个进程，每个进程用一个PCB来代表。PCB的结构为：
• 进程名——如Q1~Q5。
• 指针——把5个进程连成队列，用指针指出下一个进程PCB的首地址。
• 要求运行时间——假设进程需要运行的单位时间数。
• 已运行时间——进程已运行的单位时间数，初始值为0。
• 状态——假设两种状态，就绪和结束，用R表示就绪，用E表示结束。初始状态都为就绪状态。
(2) 每次运行之前，为每个进程任意确定它的“要求运行时间”。
(3) 把5个进程按顺序排成循环队列，用指针指出队列连接情况。用一个标志单元记录轮到运行的进程。处理器调度总是选择标志单元指示的进程运行，对所指的进程，将其“已运行时间”加1。
(4) 进程运行一次后，若“要求运行时间”等于“已运行时间”，则将状态改为“结束”，退出队列，否则将继续轮转。
(5) 若就绪队列为空，结束，否则转到(3)重复。
