采用VHDL编写的一个简单的UART

很好的学习FPGA嵌入式的资料！适合初学者和工程师参考！(Good learning FPGA embedded information! Suitable for beginners and engineers reference!)

纠错和单故障检测代码使用正交拉丁方是用VHDL语言写的。

用Verilog编写ad_9866的相应程序，在FPGA上实现相应功能(The corresponding program of ad_9866 is written with Verilog, and the corresponding functions are realized on the FPGA.)

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.)

DDR（双速率）SDRAM控制器参考设计verilog代码，可以直接用的，很好的-DDR (double rate) SDRAM controller reference design Verilog code, can be directly used, very good

matlab代码，利用Farrow结构设计分数延时滤波器，滤波器阶数和个数可分别进行设置，利用最大最小准则近似。(Matlab code, using Farrow structure design fractional delay filter, filter order and number can be set separately, using the maximum and minimum criterion approximation.)

说明：  学习fpga的工具signaltap软件使用说明书，好工具(Learn the instruction manual of signaltap software, a good tool)

在quaritusII的开发环境下，verilog语言编写的m序列发生器代码，这种算法简短而有效，非常实用。(In quaritusII development environment, verilog language of m sequence generator code, this algorithm brief but effective, very practical.)

vhdl code for 8051 processor

16次迭代的CORDIC算法，精度很高，可应用于计算反正切值(16 iterations of the CORDIC algorithm, high accuracy, can be applied to calculate arctangent)
