axi_spi_master

dds 频率可控，32位 输出为12位 已含有.hex文件，直接装载致ROM即可~(dds frequency-controlled, 32-bit output is 12 already contains. hex file can be loaded directly caused ROM ~)

实践的打井不工作，只是尚未尝试测试出多一点，不是最后的版本 ！

说明：  并行读写14路串口数据，数据被写入FIFO，在收到读写信号后，SPI发送数据出去(Parallel read and write 14 serial port data, SPI send data)

低通滤波器（由matlab和simulink两种方法实现）源文件及图片示例(Low-pass filter) source file and photo examples (by the two methods matlab and simulink)

EEPROM HDC2010温湿度传感器的verilog读写代码，IIC通信，Verilog，测试通过

这是自适应滤波器，使用verilog代码来编写的，已通过了仿真，效果很好。希望能给大家好好分享！(This adaptive filter verilog code to write, through a simulation, with good results. I hope to give a good share!)

C源碼16C550 串口驅動，使用中斷收送RS232資料(16C550 UART Driver)

基于SDRAM的PCI采集,上位机为VC编写，桥芯片为PLX9054，项目已经做完，上传5个例程，已经验证通过(SDRAM, PCI-based acquisition, PC for VC preparation, bridge chip for PLX9054, the project has been done, upload 5 routines, has been verified by)

这个是vhdl中很常见的jk filpflop的文件只用于很小数位的变化 其中的jk文件是up down运算都符合的(This is a very common vhdl jk filpflop file is only used for very small changes in a digital file which jk is up down operations are met)

说明：  此代码是由FPGA产生SPWM波的代码，简单易懂(use FPGA to generate SPWM)
