基于FPGA的32阶FIR数字滤波器设计 源程序。设计使用了并行乘法器，运行速度更快，占用内存更小，延迟更小。 (32 order FIR digital filter based on FPGA design source program. Design USES parallel multiplier, faster and less memory, less delay.)

说明：  该资料是用vhdl编写的按键消抖程序，按键消抖在使用按键的数字电路中非常重要，如果不对按键信号进行处理，有可能会出现大量错误的按键信号。文件key_xd.vhd是按键消抖程序，文件key_xd.vwf是仿真波形文件。该程序已经通过仿真测试，并且在电路板上调试通过，效果理想。(The information is written in the key consumer vhdl shaking procedures, key consumer shaking in digital circuits using the buttons is very important, if not key signal processing, there may be a lot of the wrong button signal. File key_xd.vhd is key consumer shake procedure is the simulation waveform file key_xd.vwf file. The program has been tested by simulation and debugging in circuit board by, the results are satisfactory.)

I2C verilog files. Define a simple interface of I2C.After testing to ensure the using.

用verilog实现ldpc最小和译码算法(This code is for the decode of MS-algorithm based on LDPC.)

1602是目前最常用的显示器件，本例是通过verilog 代码实现1602的显示(1602 display)

DDR2-400样例源代码，用于Xilinx Spartan 3A/3AN Starter Kit(DDR2-400 sample source code for Xilinx Spartan 3A/3AN Starter Kit)

CRC24的verilog实现,LTE的3GPP 36.212里面对应的CRC添加(the implementation of CRC24 in verilog)

有三个基于FPGA驱动高速AD/DA的程序、硬件电路图、使用向导手册、连接方法，支持ADDA_AX301，ADDA_AX415，ADDA_DB2C8，可以下载到 FPGA 黑金开发板、FPGA 黑金开发板学生版结合相关模块进行使用，

Use verilog language design DIGITAL-PID source

一份带有FIFO缓存的UART源码，采用verilog编写，实现批量数据的传输，数据缓存量可以通过修改源码中的FIFO的深度来改变。(This is a UART with FIFO. The UART is programmed using verilog, it can transmit or receive batch data. The amount of data buffered can be changed by changing the depth of FIFO.)
