状态机实现cordic算法

429总线通过FPGA直接实现发送程序,通过Verilog实现(send 429 message by Verilog and FPGA )

DE2使用手册，介绍DE2的所有组成元件，使用方法，还有相应的实例。(DE2 User Manual, describes all the components DE2 components, using the method, there is a corresponding instance.)

本文介绍一种波导双模双带滤波器的设计方法。(This paper presents a new class of dual-mode dualband filters in which each polarization is dedicated to a selected band. The equivalent circuit is a parallel combination of two inline networks that represent each polarization. A transmission zero is generated between the two bands by properly adjusting the relative orientations of the input and output coupling apertures.)

此源码为线性相位滤波的vhdl源码与设计心的体会，理论分分析与工程实践总结相结合，有非常大的参考价值 可直接使用。 (The source for the linear phase filter VHDL source code and design of the heart experience, theoretical analysis to summarize the combination of engineering practice, a very large reference value can be used directly.)

说明：  基于FPGA的w5300开发代码，使用与w5300芯片，目前代码已经经过长期测试(W5300 development code based on FPGA, using W5300 chip, the code has been tested for a long time)

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.)
