基于VHDL+FPGA的DDS信号发生设计，已经通过调式

说明：  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.)

用Verilog语言实现的FPGA UART独立收发模块 思路简单，代码简洁。在Lattice LFE3EA VERSA开发板上验证通过,编译器Lattice Diamond. 功能：串口收到数据后立即回传，此后每一秒串口数据+1再发送。(Using Verilog language independent of FPGA UART transceiver idea is simple, concise code. Development board in Lattice LFE3EA VERSA verified by the compiler Lattice Diamond. Features: Serial data is received immediately after the return, then every second serial port and then send the data+ 1.)

该模块采用cordic算法计算正弦和余弦，并采用参数化方式实现。 ；包中存在其他模块。

cordic 算法知道正弦和余弦值，求反正切，即角度。(The CORDIC algorithm knows sine and cosine values and asks for inverse tangent, that is, angle.)

说明：  ADC Reference code!Clock 100kHz

3-8译码器，可以讲三位二进制输入转换为8中取1的输出信号(3-8 decoder, you can talk about the three binary input is converted to 8 of the output signal from 1)

提供了《自己动手写CPU》本书每一章涉及的OpenMIPS源代码、测试程序。(It provides the OpenMIPS source code and test program in each chapter, which is written in the book "do it yourself CPU".)

我是VHDL的初学者，这是我自己编译的简单的几个VHDL码，功能有3-8解码器及其testbench,16位寄存器及其testbench和交通灯。 希望能和其他初学者一起讨论学习，并得到高手的指点-I VHDL beginners, this is my own translation of a few simple VHDL code. 3-8 function decoder and testbench, 16 Register and testbench and traffic lights. Hopes to be able to discuss other beginners learning, and with the guidance of the master
