Description: 电子琴的汇编语言实现，利用TPC-H实验箱上的8253实现二级分频，同时配合以8255A，与门和DAC0832，通过扬声器放音，实现两个八度音高（包括半音）的电子琴。在软硬件相互配合下，电子琴具有弹奏和播放已存乐曲的功能，音长可控，播放速度可选，拥有美观的图形界面模拟真实琴键，且琴键随弹奏有起伏变化。利用微机内部的8253，8255A和内置扬声器，与TPC-H实验板上的8255A和LED，实现节拍器，可产生长度和速度可控的2/4拍，3/4拍及4/4拍等，LED和内置扬声器同时对节拍进行提示。-Electronic organ of the assembly language implementation, the use of TPC-H test me on the 8253 frequency sub-2 implementation, in order to simultaneously meet the 8255A, with the door and DAC0832, playback through the speakers, both realize octave pitch (including half-tone) in Electronic organ. Hardware and software at each other under the Electronic organ has played and play has kept the function of music, sound long-controllable playback speed options, with aesthetically pleasing graphical interfaces simulate the real keys, and keys have their ups and downs playing with. The use of microcomputer internal 8253,8255 A and a built-in speaker, with the TPC-H test plate 8255A and LED, metronome implementation can have a controllable length and speed of 2/4 beat, 3/4 beat and 4/4 beat and so on, LED and built-in speaker at the same time on the beat to carry out prompt.

Description: 本源码为凌阳61开发板的使用例程,主要测试语音识别的功能。
工程名称： Guard_SD.spj
功能描述: 该程序是特定人辨识的一个范例：
在程序中我们通过三条语句的训练演示特定人连续音识别，其中第一条语句为触发命令。
在程序一开始为训练名称，即触发命令，然后提示训练两条命令，训练完毕开始辨识当识别
出触发名称后，发布命令则会听到应答。-The source code for the Sunplus 61 development board' s use of routines, the main test speech recognition feature. Project Name: Guard_SD.spj Function Description: This program is an example of a specific human identification: In the process we have adopted three statements of training demonstration Independent Continuous tone recognition, in which the first statement in the trigger command. Start a training program name, that is triggered by a command, and then prompts training for two orders, began to recognize when training is completed to identify triggers name, issued an order will hear the answer.

Description: xwch_test.m是主测试文件；biaoji.mat存放滤波器系数；xiangweicha.m用FFT计算相位差。
仿真框架为：
1.标记信号和双音信号续接作为发送信号；
2.对双音中一个频率分量的相位做偏移，再经过一个低通滤波器（引入线性相位，模拟收发不能同步测量现象）后，作为收到的信号；
3.用一个检测信号对收发信号进行相关运算；
4.画出收发信号以及相关处理后的信号。找出相关信号的那个尖点，从而推算出收发双音信号0相位点；
5. 输入0相位点位置，计算相对相位差。-xwch_test.m is the main test file biaoji.mat store filter coefficients xiangweicha.m calculated using FFT phase difference. Simulation framework: 1. Mark signals and then as a two-tone signal continued to send signals 2. On a two-tone frequency components of the phase shift to do, and then through a low pass filter (the introduction of linear phase, simulation can not simultaneously send and receive measuring the phenomenon), the as received signal 3. using a detection signal of the transceiver signal correlation operation 4. draw send and receive signals and related processed signal. Correlated signal of the cusp, which calculate the two-tone signal transceiver 0 phase point 5. Enter 0 phase point position, calculate the relative phase difference.
