5×5滤波器，使用Xilinx的Sytem Generator For DSP实现。滤波效果显著。-5 x5 filter, use the Generator Xilinx Sytem For DSP realized. Filtering effect is remarkable.

采用spi接口读取adc数据，存储数据，将数据进行中值滤波处理，最后通过总线接口发送到dsp处理器-spi interface adc sample program with middle filter process.

利用DSP配合FPGA为硬件架构，以DSP为数据处理核心，通过FPGA对USB、ADC和DAC等外围设备进行控制，并可实现频谱分析、数字滤波器等数字信号处理算法。(With DSP and FPGA as the hardware architecture and DSP as the data processing core, the peripheral devices such as USB, ADC and DAC are controlled by FPGA, and the digi
