FPGA开发板上实现秒表计数器功能

几个fpga竞赛的设计例-Several Example FPGA design contest

这是一篇现代通信原理课程的作业报告.题目为几种时频分析方法比较及应用.详细介绍了短时傅里叶变换、小波变换、魏格纳—威利分布和Cohen类时频分布这4种典型时频分析方法,并作了比较(This is a modern communication Principle operating report. Entitled Comparison of several time-frequency analysis and 应用. 详细 Jieshao the short time Fourier transform, wavelet transform, Wigner- Willie distribution and frequency distribution of Cohen Lei This four kinds of typical time-frequency analysis method, and compared)

一个计算机原理课程设计的作业，5级流水线CPU，指令集到代码均为自己设计，有最终报告文档，组建说明，并行除法，16位字长，定长指令，Verilog源代码，顶层设计图。结构简单，冲突解决方式也很简单，代码量小。(A computer theory course design work, five pipelined CPU, instruction set to the code are design, the final report documents the formation of parallel division, 16-bit word length, fixed-length instructions, Verilog source code, top level design. Simple structure, conflict resolution is also very simple, a small amount of code.)

用verilog实现的buffer，经过了fpga平台验证。(Implement buffer with verilog.)

学习VHDL语言的范例，有关FSK-VHDL language learning paradigm, the FSK

在matlab中8psk的调制和解调仿真程序(the modulation and demodulation of 8psk)

开发工具是quartus II 7.0以上版本，这是一个verilog语言的分频器设计，个人作业设计，供参考学习(verilog，quartus II 7.0)

FPGA开发超声波测距，可改写工业探伤或倒车测距等系统，quartus2下选择EP2C5Q208C8（CycloneⅡ） 支持目前淘宝上能买到的所有4-5针超声波模块 应用cycloneⅡ自带除法模块 开发板为有光技术YG2.1 生成电路规模较小 ！！注意：移植程序仅需重新约束数码管和超声波模块的针脚 (Ultrasonic Ranging FPGA development, industrial inspection or reverse rewritable ranging systems, EP2C5Q208C8 (CycloneⅡ) under quartus2 4-5 needle ultrasonic module supports all currently scouring the treasure can buy Applications cycloneⅡ own division module Development board bright technical YG2.1 Small scale generating circuit ! ! Note: The migration program only re-constraint digital and ultrasonic modules Pin)

说明：  多摩川绝对值编码器的NRG协议源代码,我们公司用的，我修改的解码程序(Tamagawa NRG absolute encoder protocol source code, used by our company, I modified decoding process)

ofdm系统的matlab实现，包括插入导频信号和循环前缀(Matlab implementation of ofdm system, including inserted pilot frequency signal and the cyclic prefix)
