抓取CPUID的程序反汇编的源代码，CPUID可以用来读取一些CPU的相关信息-Crawling procedure CPUID disassemble the source code, CPUID can be used to read some CPU related information

1，消除按键的抖动问题 因为按键在闭合或断开过程中出现一段抖动期，主要由于按键的不稳定性引起的，这时会呈现一串页脉冲，时间的长短和开关的机械特性有关。一般在5ms~10ms之间。为保证CPU对键的一次闭合作一次处理，必须去抖动。在键的稳定闭合或断开时读键的状态。 2，据EICE51原理图编写并调试一个键输入子程序，其功能为判断键盘上有无键输入，若有键入，作去抖动处理后，计算输入键的键号送累加器A。-eliminate jitter button issues as keys or disconnect the closure process for some jitter period, mainly due to the instability of the keys to the cause, then it will result in a bunch of pages pulse, the duration and switches on the mechanical properties. General ~ 10ms between 5ms. To ensure that the CPU in a pair of keys a close cooperation, must go jitter. The key to the stability closed or disconnected when reading the key state. 2, EICE51 schematics prepared and debug a key input subroutine, and its function of determining whether keys on the keyboard input, if typing for to handle jitter, the admission of Bond, Bond sent accumulator A.

霍夫曼编码，根据给定权值创建赫夫曼编码，显示每一步如何进行及所得编码-Huffman coding, according to the weight given to create Huffman codes, showing how each step and the resultant code

DIALOGIC 会议的测试代码，很有用的，希望对你有帮助。 -Dialogic meeting the test code, very useful, I hope you have help.

很详细的红外学习并储存24c64的汇编子程序，在设计中只要修改一下I/O调用它就可以了，是本人的工程验证能学习市面常用的绝大部分红外线遥控器。-Very detailed study of the infrared and save 24c64 compilation of subroutines, as long as in the design changed a bit I/O can call it, is my proof to study the vast majority of the market commonly used infra-red remote control.
