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.)

该项目是用VHDL编写的，并在Nexys2板套件的4个七段显示器中显示一个测微计的秒、分和小时。时间可以在开关0中停止，在按钮0中复位。显示方式与显示方式不同最小：分段到hr:min通过切换开关1

基于cordic算法的DDS的Verilog代码。经过仿真验证，绝对可靠。(Based on cordic algorithm DDS Verilog code. Through the simulation, is absolutely reliable.)

通过VERILOG编写的AD9516时钟芯片SPI配置代码(CONGIGURE THE ad9516)

说明：  SPI协议的芯片验证VIP,用UVM搭建平台验证代码(Chip verification VIP of SPI protocol, build platform verification code with UVM)

本程序调试了TI的高精度模数转换芯片ADS1115,此模数转换器采用双积分型，16位，为IIC通信方式，调试较复杂，在对直流采集方面有着广泛的应用(This program debugging TI s high-precision analog-digital conversion chip ADS1115)

能够成功的实现走马灯功能，使LED循环亮灭(To succeed the implementation of the version function, make the LED circular light out)
