PS2键盘LCD显示控制器的vhdl代码，很难得(PS2LCDController vhdl code)

数字频率测量器，脉宽测量器。可测量多种频率波形的脉宽。(Digital frequency measurement device, pulse width measurement device. Measurement of the waveform of frequency pulse width)

FIR filter up to 128x

说明：  quartus的破解软件，里面有说明文档(Quartus crack software, which contains documentation.)

用VHDL语言写的VGA核心,是个很好很齐全的核心,有很多功能.-write VHDL VGA core, is a very good subset of the core, has a lot of functions.

QAM调制，基于FPGA的实现，包含有乘法器模块、升降余弦滤波器模块、QAM序列生成模块(QAM modulator,the implementation based on FPGA,include MUL、FIRCOS and QAM generate)

AD conversion using LTC1298

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.)
