vhdl语言实现的频率发生器，可以产生不同的频率

完成的是RS422信号的计数功能，并产生一定的触发信号-RS422 signals the completion of the count function, and produce a certain trigger signals

网卡的IP核，下载即可用，解压到指定目录下就可以了，参照里面的read me.-NIC

its the vhdl stuff for ddr sdram controller nice one easily understandable

说明：  基于FPGA和弦！！！音乐芯片的设计与实现！！！(Design and implementation of FPGA chip based on the chord music)

实验一：QuartusⅡ原理图输入法设计与实现一：实验要求    ①：用逻辑门设计实现一个半加器，仿真验证其功能，并生成新         的半加器图形模块单元。    ②：用实验一生成的半加器模块和逻辑门设计实现一个全加器，仿真验证其功能，并下载到实验板测试，要求用拨码开关设定输入信号，发光二极管显示输出信号。    ③：用3线—8线译码器和逻辑门设计实现函数F，仿真验证其功能，下载到实验板测试。要求用拨码开关 设定输入信号，发光二极管显示输出信号。二：报告内容

大唐电信的FPGA设计经验，内部资料，详细完整，很有参考价值-Datang Telecom

用VERILOG编写的VGA字符显示，可以在电脑屏幕上显示字符,已通过测试(Prepared with the VERILOG VGA character display, can display characters on a computer screen, has been tested)

用VHDL语言实现TDMA编码,简单，明了。看标注就可以看懂-use vhdl langhanTDMA

数字钟，简单的数电应用，电子表源程序，常用也使用-watch

this the program which can help to convert bcd code to excess3 code,the perfect circuitary has been given in this document which will lead you to understand it more properly.Reference is taken from morris mano book of digital electronics.This program can work on quatrus without any trouble.this is also used to make a final year -this is the program which can help to convert bcd code to excess3 code,the perfect circuitary has been given in this document which will lead you to understand it more properly.Reference is taken from morris mano book of digital electronics.This program can work on quatrus without any trouble.this is also used to make a final year
