本系统参照片上系统的设计架构、采用FPGA与SPCE061A相结合的方法,以SPCE061A单片机为进程控制和任务调度核心;FPGA做为外围扩展,内部自建系统总线,地址译码采用全译码方式。FPGA内部建有DDS控制器,单片机通过系统总线向规定的存储单元中送入正弦表;然后DDS控制器以设定的频率,自动循环扫描,生成高精度,高稳定的5Hz基准测量信号。-The system with reference to the design of system-on-chip architecture, used a combination of FPGA and SPCE061A approach to SPCE061A Singlechip for process control and scheduling core mission FPGA for external expansion, internal self-system bus, address decoding using the entire translated code approach. DDS has built internal FPGA controller, microcontroller through the system bus to the provisions of the storage unit into the sine table DDS controller and then to set the frequency, automatic cycle of scanning, to generate high precision and high stability of the baseline measurement 5Hz signal.

void InitGoertzel(void)
作用:初始化算法参数
用法:采用算法进行检测前执行一次,如果需要改变参数,调用SetParameter(...
void InitGoertzel(void)
作用:初始化算法参数
用法:采用算法进行检测前执行一次,如果需要改变参数,调用SetParameter()
float CGoertzel::GetMagnitude(unsigned char * sampleData, int length) //算法主接口
作用:对采集下来的音频数据用算法处理,返回一个结果
参数:sampleData-音频数据缓冲地址指针;
length-缓冲区尺寸(音频数据数量),字节数;
返回值:返回算法结果。
void SetParameter(DWORD set_SampleRate, DWORD set_TargetFreq, DWORD set_BlockSize)
作用:设置算法参数;
参数:set_SampleRate-音频数据抽样速率;
set_TargetFreq-目标信号频率;
set_BlockSize-算法数据块尺寸(采样点);
用法:调用本函数后,需要调用一次InitGoertzel(void)才会生效-void InitGoertzel (void) function: initialization algorithm parameters Usage: The algorithm performs a pre-test, if the need to change the parameters, calling SetParameter () float CGoertzel:: GetMagnitude (unsigned char* sampleData, int length)// Algorithm for the main interface role: to collect audio data from the treatment algorithm to return a result parameter: sampleData-audio data buffer address pointer length-buffer size (the number of audio data), number of bytes return value: the return of
