[Embeded Linux] budengshi DL : 0: 很多不等式在展开以后形成如下的对称形式 sigma(s1^a1*s2^a2*...*sn^an)>=sigma(s1^b1*s2^b2*...*sn^bn) （当然作为齐次不等式 a1+a2+....an=b1+b2+...bn 变量s1,s2,...sn非负）其中sigma表示对称和（也就是说一共n!项）例如 sigma(x^3)=x^3y^0z^0+x^3z^0y^0+y^3x^0z^0+y^3z^0x^0+z^3x^0y^0+z^3y^0x^0=2*(x^3+y^3+z^3) sigma(x^3y^2z^1)=x^3y^2z^1+x^3z^2y^1+y^3x^2z^1+y^3z^2x^1+z^3x^2y^1+z^3y^2x^1 （三元sigma 一共是6项）有时候我们把sigma(s1^a1*s2^a2*...*sn*an)写作 [a1,a2,...an] 例如著名的均值不等式可以写成 [n,0,0...0]>=[1,1,1...1] 又比如x^2+y^2+z^2>=xy+yz+zx 写成[2,0]>=[1,1] 本程序能比较两个完全对称不等式的大小关系。-After a lot of inequality start to form in the following symmetric form of sigma (s1 ^ a1* s2 ^ a2*...* sn ^ an)> = sigma (s1 ^ b1* s2 ^ b2*...* sn ^ bn) (of course, homogeneous inequality as a1+ a2+.... an = b1+ b2+ ... bn variables s1, s2, ... sn non-negative) that the symmetric and one sigma (ie a total of n! items) such as sigma (x ^ 3) = x ^ 3y ^ 0z ^ 0+ x ^ 3z ^ 0y ^ 0+ y ^ 3x ^ 0z ^ 0+ y ^ 3z ^ 0x ^ 0+ z ^ 3x ^ 0y ^ 0+ z ^ 3y ^ 0x ^ 0 = 2* (x ^ 3+ y ^ 3+ z ^ 3) sigma (x ^ 3y ^ 2z ^ 1) = x ^ 3y ^ 2z ^ 1+ x ^ 3z ^ 2y ^ 1+ y ^ 3x ^ 2z ^ 1+ y ^ 3z ^ 2x ^ 1+ z ^ 3x ^ 2y ^ 1+ z ^ 3y ^ 2x ^ 1 (three sigma is a total of six) at times we have sigma (s1 ^ a1* s2 ^ a2*.. .* sn* an) Writing [a1, a2, ... an] such as the well-known inequality can be written in the mean [n, 0,0 ... 0]> = [1,1,1 ... 1] and For example, x ^ 2+ y ^ 2+ z ^ 2> = xy+ yz+ zx written [2,0]> = [1,1] This procedure can compare two completely symmetrical relationship between the si

[Embeded Linux] Qt_madplay_mp3 DL : 0: MAD （libmad）是一个开源的高精度 MPEG 音频解码库，支持 MPEG-1（Layer I, Layer II 和 LayerIII（也就是 MP3）。LIBMAD 提供 24-bit 的 PCM 输出，完全是定点计算，非常适合没有浮点支持的平台上使用。使用 libmad 提供的一系列 API，就可以非常简单地实现 MP3 数据解码工作。在 libmad 的源代码文件目录下的 mad.h 文件中，可以看到绝大部分该库的数据结构和 API 等。-MAD (libmad) is an open source precision MPEG audio decoder library, support for MPEG-1 (Layer I, Layer II, and LayerIII (ie MP3). LIBMAD providing the 24-bit PCM output, is completely fixed-point calculations, is not very suitable for Supported platforms floating point using libmad offers a range of API, it can be very simple to achieve decoding MP3 data in the source code files libmad directory mad.h file, you can see most of the library the data structure and API, etc.

[Embeded Linux] ARM-UART DL : 0: ARM监视串行口，将接收到的字符发送到字符再发送给串口，即按PC机键盘通过超级终端发送数据，开发板将接收到的数据再返还给PC，在超级终端上显示。-ARM monitors the serial port, the received characters are sent to a character and then sent to the serial port, ie the PC keyboard to send data via HyperTerminal, the board will receive the data and then back to the PC, in the HyperTerminal display.
