FPGA实现打车计程系统

vhdl语言试验箱GW48的各种模式引脚图。。(vhdl language the various modes of chamber GW48 pin map. .)

说明：  使用DE2实现DDS，步骤简单，配置管脚可自查看(Using DE2 to realize DDS, the steps are simple and the pins can be self-checked.)

介绍了FPGA设计的十大准则，对初学者很有用，对于工作多年的同志，也会有整理总结的好处(Describes the FPGA design of the top ten criteria are useful for beginners, for many years comrades, there will be finishing the benefits of the summary)

通信基带信号发生器的设计，采用单片机输入频率和波形，在FPGA中实现频率和波形生成-Communications base-band signal generator design, the use of single-chip input frequency and waveform, in the FPGA to achieve the frequency and waveform generation

用VHDL语言将二进制数据转换成十进制数据，并将十进制的每一个位分离出来单独存放。使用状态机实现，程序简单，仿真效果很理想，占用可编程器件的资源较少。-VHDL language with the binary data into decimal data and decimal places separated from each store individually. Realize the use of state machine, the program is simple, simulation results are satisfactory, occupation of programmable devices have fewer resources.

说明：  基于ofdm系统的各个模块的VHDL程序，软件是用的ISE仿真的。绝对有用。(Ofdm systems based on VHDL program of each module, the software is to use the ISE simulation. Absolutely useful.)

一款介绍Soc使用的PDF文档供大家看和实践，还是有一定参考价值的！-A description Soc using PDF documents for everyone to see and practice, there are still some reference value!

说明：  包含一个ALU，实现斐波那契数列的计算。1.接受两个6位二进制输入。2.通过手动输入的时钟驱动每个周期进行一次计算。3.结果输出到led灯（使用NEXYS4开发板）(Including an ALU to realize the calculation of Fibonacci sequence. 1. Accept two 6-bit binary inputs. 2. Each cycle is driven by a clock input manually. 3. Output to LED lamp (using NEXYS4 development board))
