基于FPGA的13位Barker码的实现

说明：  quartusii软件仿真实验代码 双二选一(quartusii software simulation code for a pair of two elections)

VHDL上百实例 包括 ADDER LATCH FIPPER AND ETC..(VHDL hundreds of examples, including ADDER LATCH FIPPER AND ETC ..)

数字示波器实验，利用AD、DA和VGA三个外设来实现简易示波器，DA外设发送正弦波给AD外设，AD外设解析成数字信号将数据送给VGA外设进行显示。在VGA上可以看到DA外设发送的波形、波形频率和波形峰峰值。(In the experiment of digital oscilloscope, AD, DA and VGA are used to realize simple oscilloscope. DA peripheral transmits sine wave to AD peripheral. AD peripheral resolves into digital signal and sends data to VGA peripheral for display. The waveform, waveform frequency and peak value of DA peripheral can be seen on VGA.)

UART 变送器正以一个 8 位数据总线和 8 位地址总线。变送器 FIFO 是包含和发射机状态机包括国家： 闲着，开始的传输，传输停止的实际数据传输。UART 变送器可以连接到任何具有可配置的数据和地址总线的 UART 接收机。

fpga串口的接收程序基于verilog语言拿走不用谢。(The receiving program of FPGA serial port is based on Verilog language.)

通过matlab对于声音进行处理，实现FFT，均值，方差，中值滤波，自相关分析，白噪声等处理(Matlab sound processing, FFT, mean, variance, median filtering, autocorrelation analysis, white noise and processing)

采用倍频及1/3、1/12倍频绘制的路面不平度频谱图（自编）(Using octave and 1/3, 1/12 octave drawn road roughness spectrum (self))

本文分析了当前国内外出租车计费系统的基本组成和工作原理及主要的两种设计方式:基于单片机的设计方式和基于FPGA的设计方式；并对这两种实现方式的优点和缺点进行分析，比较后确定本系统的方案：基于FPGA的出租车计费系统的设计。(This paper analyzes the current taxi charging system at home and abroad, working principle and basic components of two major design approach: the design methods based on single chip FPGA-based design approach and the two implementations to analyze the strengths and weaknesses, After comparing the program to determine the system: FPGA-based taxi billing system.)

axi slave 模型，verilog描述，自己可以根据自己的设计适当修改。基本功能可能存在bug，不过是模型，大家可以自己稍作修改。

DSP与FPGA时序接口模块，已经经过测试，保证读写稳定(The Interface of DSP to FPGA)
