基于FPGA的交通控制器

此代码在FPGA使用VHDL了FFT的基本思想。

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.)

该计数器可以实现从0到1000的技术，程序简练执行效率高(counter1000)

FSK/MSK/GFSK/GMSK DIGITAL DEMODULATOR VHDL SOURCE CODE OVERVIEW

这是一个用vhdl编的多功能电子秒表，可以记录几个人的时间，并且可以在跑秒的时候查看记录。。〔原创〕-This is a series with VHDL multifunctional electronic stopwatch, can be recorded by several people, and that they could run in the second examined the records. . [Original]

具有先进后出的堆栈功能。此LIFO堆栈具有两个按键（write， read），按下write键后，开始输入数据data0-data3；按下read键后，7段数码管开始倒序显示data3-data0（十进制）。 高级要求（可选）： 按下write键，VGA显示“Write”字样，并同时显示输入数据；按下read键，VGA显示“Read”字样，并同时显示输出数据。

采用Quartus2编写的电子秒表电路 实现计时、暂停等功能(Quartus2 prepared using electronic stopwatch timer circuit, suspension and other functions)

用verilog编写的can总线控制器，包括设计参考历程和仿真程序，以及开发文档！(Written by verilog can bus controller, including the design reference course and simulation program, and the development of the document!)

Shift reg in vhdl, a first example to start

实现dds功能，利用quartus软件， 子模块包括加法器，锁相环，date-rom 利用原图将各模块综合，利用ps2键盘控制频率及相位。-Dds realize functions, using Quartus software, sub-modules including the adder, phase-locked loop, date-rom image to the module using integrated, using ps2 keyboard to control the frequency and phase.
