algorithm implementation in programming language

用C语言实现的傅里叶计算，硬件平台为TMS320F2812(Using C language implementation of the Fourier calculations, the hardware platform for TMS320F2812)

利用SPI接口操作norflash，从读写到擦除。

里面是GPS/INS的组合导航matlab程序，位置误差是在10m，速度误差时1m/s大家可以参考。

说明：  这是购买周立功的试验箱时候松的源代码。很经典的代码。希望学习单片机的朋友好好研究。短小精悍。有意思。这是第二部分。(This is the purchase of weeks Ligong Song of the chamber when the source code. Classic code. Singlechip friends want to learn on this issue. Dapper. Interesting. This is the second part.)

BICG算法，是Krylov子空间的迭代方法之一(The BICG algorithm is one of the Krylov subspace iteration method)

本设计是一款智能跟随机器人，和大家分享分享。

TLD算法的QT版本，没有matlab的相关代码，完全用C/C++实现，可以移植到嵌入式平台或者其他平台(TLD algorithm for the QT version, no matlab related code, complete with C/C++ implementation can be transplanted to the embedded platform or other platforms)

该系统基于QT4，Release发布后即可使用。通过下载数据库数据，本地解压，多线程进行一个数据查询、搜索的功能，可以完成自主下订单等功能。

说明：  一架飞机在海上失事，搜救人员打捞出了该机的黑匣子，技术人员从其中的内存里恢复了一段声音plane.wav，经推断该声音是失事之前最后时刻的数据，设备供应商证实该声音是通过频分复用生成后准备发送出去的，复用的其中一路信号可能含有驾驶员最后发出的指令，现在要求对该声音进行分析，并恢复可能存在的指令，同时能够利用平台实时播放提取的信号。 内含matlab和CCS两份代码(A plane crashed at sea, search and rescue personnel salvaged the black box of the plane, the technician recovered a piece of sound plane.wav from its memory, and it was inferred that the sound was data at the last moment before the crash, and the equipment supplier confirmed the sound It is prepared to be sent out after being generated by frequency division multiplexing. One of the multiplexed signals may contain the last command issued by the driver. Now it is required to analyze the sound and restore the possible instructions. At the same time, the extracted signals can be played in real time using the platform.)

说明：  图像的双线性插值放大算法中，目标图像中新创造的象素值，是由源图像位 置在它附近的2*2 区域4 个邻近象素的值通过加权平均计算得出的。 双线性内插 值算法放大后的图像质量较高，不会出现像素值不连续的的情况。然而次算法具 有低通滤波器的性质，使高频分量受损，所以可能会使图像轮廓在一定程度上变 得模糊。 (Bilinear interpolation algorithm to enlarge the image, the target image in the newly created pixel value is determined by the source image position in its area near the 4 2* 2 the value of neighboring pixels calculated by the weighted average. Bilinear interpolation algorithm to enlarge the image quality after the high pixel value does not appear the situation is not continuous. However, sub-algorithm has low-pass filter nature of the damage to the high frequency components, it may make the image contour to some extent become blurred.)
