使用vhdl实现的1024点的FFT算法

用全加器设计8位运算器逻辑电路图 2、根据逻辑电路用 VHDL编程实现 3、调试编译通过后，仿真 (this file can help you learn the design of cpu)

用CPLD驱动扬声器实现音乐的播放，程序是用VERILOG写的，-CPLD driver speakers with music player, the program is written in VERILOG,

adding custom ip EDK

这个是用verilog语言编写的基于FPGA的交通灯控制器，分别控制四个方向上的交通灯的通断-The verilog language is FPGA-based traffic light controller, respectively, the four direction control of traffic lights-off

Verilog HDL编写的键盘扫描程序，考虑了判断按键弹起的问题。程序按一定的频率用低电平循环扫描行线，同时检测列线的状态，一旦判断有一列为低则表示有键被按下，停止扫描并保持当前行线的状态，再读取列线的状态从而得到当前按键的键码；等待按键弹起：检测到各列线都变成高点平后，重新开始扫描过程，等待下一次按键。-Written in Verilog HDL keyboard scanner, taking into account to determine key bounce problem. Program according to a certain frequency of scan lines with low-level circulation lines, while testing out the state line, once the judge has said there is a classified as low-key is pressed, stop the scan and to maintain the current line-line state, and then read out line state to get the current keys key codes to wait for key pop-up: To detect the lines at all out into a high level after the re-start the scanning process, waiting for the next key.

verilog开发FPGA，实现RS485串口通信(RS485 driver for FPGA )

说明：  基于ofdm系统的各个模块的VHDL程序，软件是用的ISE仿真的。绝对有用。(Ofdm systems based on VHDL program of each module, the software is to use the ISE simulation. Absolutely useful.)

 采用quartusⅡ仿真软件实现多功能信号发生器的FPGA设计,当输入端有时钟信号输入时，各个信号发生器模块独立运行，独立存在，发出各种信号，这些信号作为数据选择器的输入信号，在数据选择器的作用下，波形切换到相应的模块输出，将通过示波器显示出相应的波形图。
