SPI的VHDL程序，经过quartus验证的，不错！

The program is used to establish communication with the pc through serial port. It utilses the inbuilt micro controller called as picoblaze for the processing for implementation on spartan 3E

利用VHDL 硬件描述语言设计一个0~9999 的加法计数器。根据一定频率的触发 时钟，计数器进行加计数，并利用数码管进行显示，当计数到9999 时，从0 开始重新计数(Use of VHDL hardware description language design a 0 ~ 9999 addition counter. According to a certain frequency of the trigger The clock, counter add count, and use digital pipes to show that when the count to 9999, starting from 0 to count )

说明：  FPGA控制AD7321的模块，是本人亲自试验过的。有Verilog源码，和简单文档。(FPGA control module of the AD7321 is personally tested. There Verilog source code, and simple document.)

利用SCCB和FPGA实现视频采集的论文，对相关开发人员具有很强的参考价值！ (FPGA implementation using the SCCB and video collection of the papers, the relevant developer has a strong reference value ! )

用于modelsim仿真的xilinxfpga平台IP库，以ise 13.x为基础制作，在modelsim10下验证通过。(xilinx IP core library for modelsim simulate, based on ise 13.x, verified in modelsim10.)

说明：  基于fpga的计数器模块 分频 可移植 完美实现(Perfect realization of frequency division and portability of counter module based on FPGA)

基于FPGA的新型数据位同步时钟提取(CDR)实现方法-New FPGA-based data bit sync clock extraction (CDR) method

这是一个在Quartus II软件中编写的vhdl程序。程序下载后可用蜂鸣器播放音乐 -This is a Quartus II software in the preparation of the VHDL program. After the buzzer can be used to download music player
