数字锁相环设计源程序
- PLL是数字锁相环设计源程序, 其中, Fi是输入频率(接收数据), 数字锁相技术在通信领域应用非常广泛，本例用VHDL描述了一个锁相环作为参考，源码已经调试过。编译器synplicty.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 freque

除法器的设计本文所采用的除法原理
- 除法器的设计本文所采用的除法原理是：对于八位无符号被除数A，先对A转换成高八位是0低八位是A的数C，在时钟脉冲的每个上升沿C 向左移动一位，最后一位补零，同时判断C的高八位是否大于除数B，如是则C的高八位减去B，同时进行移位操作，将C的第二位置1。否则，继续移位操作。经过八个周期后，所得到的C的高八位为余数，第八位为商。从图(1)可清楚地看出此除法器的工作原理。此除法器主要包括比较器、减法器、移位器、控制器等模块。-Divider design used in this paper, the p
