说明：  自己编写的一部分完整代码，是学习arm9的好工具，这个程序是针对s3c2440的。能够实现按键检测，led显示和串口的打印。(I have written part of the complete code, is a good tool for learning arm9, this program is for s3c2440' s. To achieve key detection, led display and print the serial port.)

系统侧的电压在0.04秒到0.06秒发生15％的电压跌落，在0.06 秒到0.07秒分别加入了3次和2次谐波，幅值分别为基波电压的20％和15％，相位分别为负25度和35度。(System voltage side occurs in 0.04 seconds to 0.06 seconds 15 of the voltage drop in 0.06 seconds to 0.07 seconds and 3 were added to the second harmonic amplitude of 20 and 15 of the fundamental voltage, phase, respectively negative 25 degrees and 35 degrees.)

： ：： ：针对传统麦克风阵列声源定位算法抗噪声及混响能力不强的问题，提出一种基于最小熵值和随机域压缩的麦克风阵列声源定位算 法。利用最小熵值方法对麦克风阵列进行时延估计，并与随机域压缩方法相结合，对声源进行空间搜索。仿真实验结果表明，该算法在定 位精度、抗噪声及抗混响能力方面均优于广义互相关相位变换算法。(Sound source localization algorithm based on minimum entropy microphone array)
