Verilog based on the eight

FPGA应用举例，非常适合初学者，高手莫下-FPGA application, for example, very suitable for beginners, experts, under Mo

这是我自己写的4人表决器源码，在xilinx Spartan3E 上已经调试成功，拿出来与大家分享！-that I wrote four voting machine source code, In xilinx Spartan3E debugging has been successful, with the show to share with you!

用vhdl编写的简易电子中设计，经过测试成功，且用记事本上载，无需阅读器进行阅读。-Use of VHDL in the preparation of simple electronic design, has been tested successfully, and use Notepad to upload without reader reading.

数控分频器设计:对于一个加法计数器，装载不同的计数初始值时，会有不同频率的溢出输出信号。计数器溢出时，输出‘1’电平，同时溢出时的‘1’电平反馈给计数器的输入端作为装载信号；否则输出‘0’电平。 -NC divider design : an adder counter, loading the initial count value, have different frequency output signal of the overflow. Counter overflow, the output"1 "Level, Overflow at the same time the"1 "level feedback to the counter input signal as loading; Otherwise output"0 "level.

FPGA的测频程序，用了D触发器，能测1hz到几百hz(FPGA frequency measurement procedures, using a D flip-flop, can be measured to a few hundred hz 1hz)

altera mvb fpga sopc 设计参考文档，有一定价值(mvb fpga sopc Design scheme)

RS[255,223]纠错码verilog源码，包含编码和解码模块，以及testbench等。(Verilog source code for RS[255,223] encoder and decoder, with testbench included.)

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))

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.
