利用两个半加器来组成的全加器，是简单的vhdl语言入门

这个程序是基于等精度测频原理的频率计，用VHDL语言实现，频率测量测量范围1~9999；用4位带小数点数码管显示其频率，并且具有超量程、欠量程提示功能。-This procedure is based on the principle of frequency measurement accuracy, such as the frequency meter, using VHDL language, frequency measurement range 1 ~ 9999 with four decimal places with the frequency of the digital display and has a super-range, less range prompts.

以ISE为开发环境，Verilog语言编写程序。功能：FPGA控制 LCD_1602动态显示秒表(In the development environment of ISE, Verilog language is used to write programs. Function: LCD_1602 dynamic display stopwatch controlled by FPGA)

NiosII的C代码,包括网卡,lcd,usb,串口,按键.(NiosII C code, including network cards, lcd, usb, serial, key.)

设计一个十进制计数器模块，输入端口包括 reset、up_enable 和 clk，输出端口为 count 和 bcd，当 reset 有效时（低电平），bcd 和 count 输出清零，当 up_enable 有效时（高电 平），计数模块开始计数（clk 脉冲数），bcd 为计数输出，当计数为 9 时，count 输出一 个脉冲（一个 clk周期的高电平，时间上与“bcd=9”时对齐）(Design of a decimal counter module, input port, including the reset up_enable clk, output port for the count and bcd, when reset is active (low), the bcd and count output cleared up_enable active (high), count module starts counting the (the CLK pulse number), the BCD count output when the count 9, the count output of the high level, the time of a pulse (a clk cycle with " bcd = 9" when aligned))

维特比译码，卷积编码，verilog编写，2,1,2编码(Victor than decoding, convolution code, verilog write, 2,1,2 coding )

基于FPGA与LM4550B的AC97软声卡VHDL语言驱动，版本2.0-FPGA-based soft and LM4550B the AC97 sound card driver VHDL language, version 2.0

这里面有许多vhdl的例子，相信对这语言的初学者受益匪浅-There are many examples of vhdl, I believe that beginners benefit from this language
