de2的简单例程led

说明：  基于FPGA的16QAM调制解调设计，以及仿真实现(Design of 16QAM Modulation and Demodulation Based on FPGA)

介绍 verilog 语言，用于实现包括乘法计算两个 32 位数字。在码，我输入我的 CWID 和 41411 来验证功能。您可以更改要计算不同的值的十六进制文件。体系结构 ︰ 携带-波纹 + 进位跳跃。

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.)

Wimax矩阵的LDPC编码器，已通过modelsim仿真测试，并前在altera的FPGA板上通过测试,码率5/6，可进入代码内部修改参数，支持2/3,3/4其他2个码率，数据吞吐量为700M(Wimax based LDPC encoder, modelsim simulation passed, also passed on altera FPGA board, code rate 5/6, also support 2/3,3/4, throughout 700m)

本代码用verilog语言配合sopc和nios实现了串口调试的目的。软件编程用C语言描述，只是比较简单的例子，适合初学者做了解用，本人亲自在EP2C8Q上实践。(The code to use verilog language sopc and nios achieved with serial debugging purposes. Software programming using C language description, but relatively simple example for beginners to do with understanding, I personally EP2C8Q on practice.)

说明：  可以实现2PSK的信号调制，已经过Modelsim波形仿真(It can realize 2PSK signal modulation and has been simulated by Modelsim waveform.)

verilog编写的SDRAM实验，有串口调试助手和相关资料！！！！！！！！！！！！！！！！！！！！！(Verilog prepared by the SDRAM experiment, a serial debugging assistant and related information!!!!!!!!!!!!!!!!!!!!!)

ecc椭圆算法RTL,verilog源代码经过验证，用于FPGA或者ASIC(ECC elliptic curve encryption algorithm for Verilog implementation)

RS编码器在fpga上的实现，用的modelsim开发环境(RS encoder in the realization of the fpga, development environment used in modelsim)

此代码是实现DPA。
