说明：  这里是apb总线设计代码。这个源程序是基于verilog语言设计的(Here is the APB bus design code. This source program is designed based on Verilog language)

图像降噪GUI界面，用到butterworth滤波器，中值滤波器和维纳滤波器，仅供参考。(noise reduction using media filter )

多个VHDL编码的例题，详细的电路图介绍，还有流程图-many examples of VHDL code, the particular introduction of circuit diagram and flow chart

基于FPGA的实现小数倍分频代码，广泛应用于数字通信中。-FPGA-based implementation of a small multiple of sub-frequency code, widely used in digital communications.

数字钟vhdl主要分为正常显示与报时功能(Digital clock vhdl)

基于FPGA器件的DDS设计实现中的一个核心部分就是波形存储表的设计。首先采用LPM_ROM和 VHDL选择语句这两种方法进行波形存储表的设计和比较分析 然后考虑到硬件资源的有限性及DDS的精度要 求,对这两种方法的程序进行了优化 最后对这两种方法设计的程序进行仿真和硬件调试。结果表明:采用这两种 方法都能有效地实现DDS中波形存储表的设计。 (DDS-based FPGA devices designed to achieve one of the core of the waveform is stored in table design. First of all, choose to adopt LPM_ROM and VHDL statements of these two methods for the design waveform storage tables and comparative analysis and then, taking into account the limited hardware resources and the accuracy of DDS, the two methods to optimize the process the last of these two methods of process design simulation and hardware debugging. The results showed that: the use of these two methods are all effective ways to achieve the DDS waveform stored in the table design.)
