_2FFT Algorithm

EDA技术以EDA软件工具为开发环境，以可编程逻辑器件为实验载体，实现源代码编程和仿真功能。VHDL作为一种标准化的硬件描述语言用于描述数字系统的结构、行为、功能和接口。本设计提出了一种基于VHDL语言的编码器和译码器的实现方法。编码器与译码器是计算机电路中基本的器件，本课程设计采用EDA技术设计编码和译码器。编码器由8线-3线优先编码器作为实例代表，译码器则包含3线-8线译码器和2线-4线译码器两个实例模块组成。课程设计采用硬件描述语言VHDL把电路按模块化方式进行设计，然后进行编程、时序仿真和分析等。课程设计结构简单，使用方便，具有一定的应用价值。 (EDA technology take the EDA software as tools for the development of the environment,programmable logic devices in experimental carrier,the realiztion of the source code programming and simulation. The VHDL as a standardized hardware description language used to describe the struction of digital systems,behavior,function and interface. The paper proposes a method for encoder and decoder based on the VHDL language.Encoder and decoder is a basic computer circuit devices.This Curriculum design by EDA design encoder and decoder.Encoders from 8- 3 priority encoder for example,and decoder includes 3- 8 decoder and the 2- 4 examples of the two decoder modules.And then to program, the timing simulation and analysis.Curriculum design, simple structure, easy to use and has a value.)

ALTERA嵌入式设计大赛获奖作品文章，非常适合DE2开发参考-ALTERA Embedded Design Competition Prize-winning article, very suitable for the development of reference DE2

只需要FPGA两个通用管脚，就可以实现FPGA与PC机进行以太网通信！！如果你有ALTERA_DE1的开发板，可以直接下再看效果，用其他板子就要重新分配一下管脚，推荐使用电流输出。-Only two general-purpose FPGA pins, you can realize FPGA and Ethernet PC machine! ! If you have ALTERA_DE1 development board, you can look under the direct effect, with other board you will need to reconsider the distribution of pins, recommended the use of current output.

TCM解码，VHDL代码，是我在工作中做的工程代码，时序稳定，里面有syn以及软判决的算法，经典-TCM decoder, VHDL code, yes, I do work in the project code, timing stability, There are syn and soft-decision algorithm, classic!

一个数码管的驱动开发程序，程序完备，可以直接使用，在开发板上使用时注意改变引脚(A digital control of the driver development program, the program is complete, can be used directly, when used in the development of attention to change the pin board)
