VHDL
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.)

cordic_atan
说明： 用verilog语言实现计算反正切函数，在软件无线电中解调PM/FM中使用的尤为频繁。上传的压缩包是modelsim工程，基于6.5c,里边包含一个完整的PM波产生以及解调过程的matlab文件仿真，并取其中间的I和Q支路做为verilog文件的输入，并将其借条输出与MATLAB实际解调输出作比较。
鉴相器的设计基于CORDIC算法，其精度取决于迭代的深度。由于工程实际运用只需要解调出atan值，并不需要绝对的值，所以并没有给予加权，需要的同学可以自己加上。(Calculated using verilog language arc tangent function, the software radio demodulation PM/FM is particularly used frequently. From the archive is modelsim project, based on 6.5c, inside the PM contains a complete demodulation process of wave generation and simulation matlab file, and whichever is the middle of the I and Q branch verilog file as input, and its IOU demodulated output and actual output of MATLAB for comparison. Phase detector design is based on CORDIC algorithm, its accuracy depends on the iteration depth. As the practical application of engineering demodulated atan value only and does not need absolute value, and there is no weight given to the need of the students can add their own.)
