对于在dsb系统中进行通信所以实现的硬件仿真和验证，对大家有一定的帮助谢谢

数字钟电路的实现，可以24小时计时，可调整时间！(Digital clock circuit implementation, a 24-hour timer, adjustable time!)

通过一个计数器来实现输出信号的占空比要求，可以将duty_cycle分配到拨码开关上,LED分配到发光二极管上,然后调节拨码开关,即可看到LED的亮度发生变化.(The duty cycle of the output signal can be assigned to the dial switch by a counter, and the LED can be assigned to the light emitting diode. Then the brightness of the LED can be seen by adjusting the dial switch.)

The Date prototype object is itself a Date object (its [[Class]] is "Date") whose value is NaN.

串uart的vhdl，verilog，lattic实现原码 里面有四个文件,分别UART 源码 (lattice version)uart 源码 (Verilog)uart 源码 (VHDL)uart16550.tar-uart series of vhdl and verilog. lattic achieve the original code, there are four documents, Source respectively UART (lattice version) uart source (Verilog) uart source (VHDL) uart16550.tar

一种基于格雷码的异步FIFO设计与实现,8*8位的fifo VHDL 源码-Gray-code based on the Asynchronous FIFO Design and Implementation

PLL是数字锁相环设计源程序, 其中, Fi是输入频率(接收数据), Fo(Q5)是本地输出频率. 目的是从输入数据中提取时钟信号(Q5), 其频率与数据速率一致, 时钟上升沿锁定在数据的上升和下降沿上；顶层文件是PLL.GDF-digital phase-locked loop PLL design source, in which Fi is the input frequency (receive data), Fo (Q5) is the local output frequency. Objective is to extract data input clock signal (Q5), its frequency and data rate line, the clock rising edge of the lock data the rising and falling edge; top-level document is PLL.GDF

Implement LMS vhdl code.
