PID控制规律及控制器实现

中值滤波算法的verilog实现，可用于相关算法在基于FPGA的嵌入式图像处理系统中。(Median filtering algorithm verilog realization available FPGA-based embedded image processing system.)

用FPGA开发板的按键作为电子表的时间初值设置控制信号，数码管当前时间值输出。用按键选择分别输出：分、秒、1/10秒。(With FPGA development board button, as the time value of the electronic table, set the control signal, digital tube current time value output. Select output by buttons: minutes, seconds, and 1/10 seconds.)

利用QuartusⅡ6.0对所设计的出租车计费器的VHDL代码进行仿真，并在FPGA数字实验系统上实现了该控制。(The Quartus II 6 is used to simulate the VHDL code of the designed taxi billing device, and the control is realized on the FPGA digital experiment system.)

配置GTH ip的例子工程，选用7 series 芯片的GTH 113quad的四个通道，在程序中每个链路利用自己的恢复时钟进行数据解码，所以四个通道可以各自独立运行；成功工作在2.54Gb/s的链路状态，长时间（>24小时）的测试，误码率一直为0.(The GTH ip example project is configured with four channels of the GTH 113quad of the 7 series chip. Each link in the program uses its own recovery clock for data decoding, so the four channels can operate independently; the successful operation is at 2.54Gb/ The link state of s, long time (>24 hours) test, the bit error rate has been 0.)

通信中卷积交织/解交织FPGA源程序，采用verilogHDL代码实现，包含测试程序，经过验证。(Communication in the convolutional interleaving/de interleaving FPGA source program, using verilogHDL code to achieve, including test procedures, after verification.)

串行流水线格式:使用COrdic 算法计算反正切:向量模式下求角度 16bit :数据全部补码格式 (Serial line format: Use COrdic algorithm arctangent: seeking angle vector mode 16bit: full complement data format)

说明：  ds18b20的Verilog程序，经测试验证可以使用。注意此版本为DALLS DS18B20而不是DS1820,注意加5K上拉电阻。(ds18b20 the Verilog process can be used to verify by testing. Note that this version rather than DALLS DS18B20 for DS1820, the attention of Canadian 5K pull-up resistor.)

AD9469 FPGA 代码  软件无线电前端 AD9469 Verilog 代码  FIFO后数据处理等

说明：  使用FPGA实现RGB图像转灰度图像的算法，下载入自己的电路板可直接将摄像头拍摄到的图像实时转换成灰度图像(FPGA is used to realize the algorithm of transforming RGB image into gray image. The image captured by the camera can be converted into gray image in real time by downloading it into its own circuit board)
