verilog分频器～时钟为50hmz，波特率采用9600bps～-Verilog clock divider ~ 50hmz, using baud rate 9600bps ~

10对于进入密码锁的按键，假设复位后七个灯显示0，使用sw1、sw2两个键输入，只要按sw1键，并使七个灯显示每秒速度加1的值，但释放sw1键后停止。

SRAM读写测试，每秒进行一次单字节SRAM读写，使用chipscope观察时序波形(SRAM read and write test, a single byte SRAM read and write every second, using chipscope to observe the timing waveform)

IEEE1588de FPGA 程序，已测试，可直接用，方便(IEEE1588de FPGA program has been tested, can be directly used to facilitate)

此源码为线性相位滤波的vhdl源码与设计心的体会，理论分分析与工程实践总结相结合，有非常大的参考价值 可直接使用。 (The source for the linear phase filter VHDL source code and design of the heart experience, theoretical analysis to summarize the combination of engineering practice, a very large reference value can be used directly.)

This application note explains the process of eveloping and debugging a hardware abstraction layer (HAL) software device driver, to aid device driver development for the HAL of the Altera Nios® II system. The various software development stages are illustrated using the Altera_Avalon_UART as an example hardware device, and an example of a HAL software device driver called my_uart.-This application note explains the process of eveloping and debugging a hardware abstraction layer (HAL) software device driver, to aid device driver development for the HAL of the Altera Nios® II system.

MODELSIM的实验程序，在QUARTUSii中调用MODELSIM，实现仿真-ModelSim Experimental procedures QUARTUSii call MODELSIM, realize Simulation

这是在 vhdl 的简单循环的拳头在后进先出队列。缓冲区的大小和数据大小可以通过 N 和 W 的参数配置。队列最前面的是可用输出数据。两个信号控制写入和读取数据。如果缓冲区是空的还是满的两个输出信号信息。

说明：  电网协议信道解交织器设计FPGA实现，适用于PB16的宽带电力线载波通信(Grid protocol channel deinterleaver design FPGA implementation, suitable for PB16 broadband power line carrier communication)
