Abstract Raw audios contain significant amount of rendancy which can be used for
steganographic purposes. But practically most audios are stored and transmitted in the
compressed formats. In this paper, we present a MPEG-1 Layer III (MP3) audio CODEC
based steganographic method to embed secret message ring encoding. The Huffman
tables in MP3 standard are first partitioned into three groups. The secret message is then
embedded by Huffman table swapping strategy. Instead of fully decoding the stego-audio,
the extraction of the secret message can be done just by parsing the side information. The
proposed method is designed under the restrictions of the MP3 compression standard
without any modifications or additions to the existing standard. Experimental results show

MCS-51单片机指令系统集(英文注释)
原先帖子(内容相同)的被锁定了!各位,不好意思啊!麻烦宋老师把原先的开掉!
MCS-51指令系统集(英文注释)
若帖子中若有疏漏或谬误之处,敬请及时批评指正,以免误导真正“新手上路”的年轻小虾们!

SWAP (Swap) 低4位与高4位交换;
(4)控制转移类指令(17种助记符)

LCALL(Long subroutine Call)子程序长调用;
RET(Return from subroutine)子程序返回;
RETI(Return from Interruption)中断返回;
SJMP(Short Jump)短转移;
AJMP(Absolute Jump)绝对转移;
LJMP(Long Jump)长转移;
CJNE (Compare Jump if Not Equal)比较不相等则转移;
DJNZ (Decrement Jump if Not Zero)减1后不为0则转移;
JZ (Jump if Zero)结果为0则转移;
JNZ (Jump if Not Zero) 结果不为0则转移;
JC (Jump if the Carry flag is set)有进位则转移;
JNC (Jump if Not Carry)无进位则转移;
JB (Jump if the Bit is set)位为1则转移;
JNB (Jump if the Bit is Not set) 位为0则转移;
JBC(Jump if the Bit is set and Clear the bit) 位为1则转移,并清除该位;
NOP (No Operation) 空操作;
(5)位操作指令(1种助记符)
SETB(Set Bit) 位 置1 。
下次抽空将各条指令的用法,用我自己地话(个人的理解),再来“牛”一下,以供参考。同时,我也很希望各位大虾,多“出版”一些高质量的好东东(包括学习心得),最好系统些。给像我这样的班门弄斧的小虾,做做榜样,引引路,好让真正“新手上路”的单片机爱好者少走弯路,我想,这时我们单片机初学者共同的心声!所谓愚者千虑,必有一得,我们小虾们,在学习中发现的东东多往上帖帖,就当作是练习吧!
互相协作!
5. 基于51单片机的自动洗衣机外文科技文献
自己去sciencedirect,springerlink等外文数据库下载啊
或者到知网,维普等中文数据库下载
很多的,校园网内免费获取
校园网外可以利用google学术搜索,有部分能免费下载
6. 单片机英文文献及翻译,2200字左右
Single-Chip Microcomputer
有的时候,也可以用SingleChip来代替

单片机是把主要计算机功能部件都集成在一块芯片上的微型计算机。它是一种集计数和多中接口于一体的微控制器,被广泛应用在智能产品和工业自动化上,而51单片机是个单片机中最为典型和最有代表性的一种。
本课题选择89S51为核心控制元件,设计了一个日常生活中用到的电子音乐门铃系统。当功能按键按下,音乐响起,发光二极管随着音乐的节拍进行闪烁,LED显示相应的定时器初值。音乐演奏过程中再次按下按键无效,只有当音乐段结束再次按下才有效。如果是电子音乐门铃在响,按下复位按键就终止,显示初始状态。经过实践证明,本系统运行稳定,具有一定的实用价值。

SCM is a major piece of computer components are integrated into the chip micro-computer. It is a multi-interface and counting on the micro-controller integration, and intelligence procts are widely used in instrial automation. and MCS-51 microcontroller is a typical and representative.
The topics chosen for the 89S51 control of the core components used in the design of a daily electronic music doorbell system. When the function button is pressed, the music sounded and the music beats with light emitting diodes for flickered. Initial corresponding LED timer. Musical process again pressed the button ineffective, and only when pressed again before the end of the music effectively. If the doorbell ring for electronic music, press the button on the rection and termination, showed initial state. Practice has proved that the system is stable and has some practical value.
本设计是以凌阳16位单片机为重心,介绍语音控制在机械手中的应用,实现微型舵机的运作,完成所指定的动作。其中通过凌阳16位单片机输出的脉冲信号来准确的控制机械手的摆动角度,机械手的捏拿动作由电磁铁完成,电磁铁的通断由凌阳16位单片机的I/O口控制,硬件和软件都在具体的实验中证明了其可行性
