FPGA

zedboard原理图详细，PCB板焊接方便，每个接口表明清楚。(Zedboard schematic in detail, PCB board welding is convenient, each interface that clearly.)

能实现数字钟中时间的显示，并可对小时，分钟，秒进行调整-Can realize the time digital clock display, and on the hours, minutes, seconds to adjust

这是脉冲宽度调制技术的VHDL代码，包括一个比较器，正弦波发生器，锯齿波发生器，脉冲宽度调制器等。

应用VHDL语言将高稳晶振分频得到1pps，使用GPS的1pps信号作为触发-Application of VHDL language high stability crystal oscillator frequency to be 1pps, the use of GPS signals as a trigger of 1pps

说明：  一个编码解码系统，其中包含一个信号发生器（用查找表方式实现）、一个m序列生成器（用来编码和解码用）、一个FiFo队列用来做缓存以及用串口方式进行收发读取数据。(An encoding and decoding system, which includes a signal generator (implemented by look-up table), an m-sequence generator (used for encoding and decoding), a FIFO queue for caching, and a serial port for receiving, transmitting and reading data.)

能够实现 LCD时序驱动,通常cpu送出的信号为data bus信号，液晶屏幕并不能正常显示，需要lcd driver(LCD timing controller, usually cpu send out the data bus signal, so the lcd driver can t display normally, need the driver)

利用Verilog语言中的函数调用实现阶乘运算的功能(Function calls use Verilog language implementation of the factorial function computing)

stc12c5a60s2单片机做的两路呼吸灯，可以用ad和按键控制闪动频率(stc12c5a60s2 SCM done with the two breathing lights, you can use the ad and buttons to control the flashing frequency)

基带数字信号通过成形滤波（选用升余弦滚降函数）然后进行载波调制(Base-band digital signal through the shaping filter (raised cosine roll-off optional function) and then proceed to carrier modulation)
