基于FPGA设计的电子密码锁是一个小型的数字系统，与普通机械锁相比，具有许多独特的优点：保密性好，防盗性强，可以不用钥匙，记住密码即可开锁等。(FPGA-based design of the electronic code lock is a small digital system. It has many unique advantages：good privacy and security , it do not need the key but remember password to unlock, and so on while it compare to ordinary mechanical locks.)

程序在报告中，要　用QuartusII运行，注意从word到运行环境中，可能有个别符号不兼容，重新在运行环境中输入那些符号就可以了-procedures in the report, with QuartusII operations, the attention to word from the operating environment, Some individual symbols are not compatible, the operating environment to re-enter those symbols on the

calculate min max of series of nb

说明：  一个简单的键盘接口模块程序，对键盘输入的数据和时钟信号进行过滤。过滤后的数据信号PS2Df将被送入两个11位移位寄存器中(A simple keyboard interface module program filters keyboard input data and clock signals. The filtered data signal PS2Df will be fed into two 11-bit displacement registers.)

广东工业大学硕士论文《SVPWM算法优化及其FPGA/CPLD实现》，在详细分析经典SVPWM算法基础上，提出一种优化算法，并在FPGA上实现。论文附录包含VHDL源码。(Guangdong University Thesis " SVPWM algorithm to optimize its FPGA/CPLD realization" in the detailed analysis of the classical SVPWM algorithm is proposed based on an optimization algorithm, and implemented on FPGA. Paper appendix contains VHDL source code.)
