编程规范是重中之重，带你书写良好的变成习惯(It is used to measure noise and detect road noise pollution. It is accurate and has good effect.)

实现verilog16位乘法器，verilog新手(achieve 16-bit multiplier)

VHDL实现快速傅里叶变换，内附带资料以及源代码。(VHDL fast Fourier transform, within the supplied data and source code.)

Configurable cpu core that supports Z80, 8080 and gameboy instruction sets

this is the source code we have been working on for our project using altera de2 board. the code can be run but some of it miss the end game module, while some doesn t have the complete vga code

可以实现2PSK的信号调制，已经过Modelsim波形仿真(It can realize 2PSK signal modulation and has been simulated by Modelsim waveform.)

VHDL语言编写的计数器程序，实现1到9999计数，并动态扫描显示，带清零和暂停功能，课上作业自编程序-VHDL language of the counter program to achieve 1-9999 counts, and the dynamic scan showed, with Clear and suspension of functions, classes, on a self-compiled programs

简易函数发生器，能产生正弦波，三角波，梯形波，方波，并且可调频率和幅度值。(Simple function generator can produce sine, triangle wave, trapezoidal wave, square wave, and the adjustable frequency and amplitude values.)

俩个比较好的计数器的vhdl代码：一个是n位通用计数器，一个是的用到的语法比较全面。是比较好的学习资料-Both a relatively good counter VHDL code: one is the generic n-bit counter, one is the syntax used in the more comprehensive. Is a better learning materials

 本程序应用VHDL硬件描述语言，以QuartusⅡ8.0为开发工具设计了一个具有自动演奏乐曲功能的系统，演奏乐曲为《梁祝》，具有单曲播放器功能。本程序简单易懂，可作为FPGA入门学习之用。
