负数的三重移位

基于FPGA的fsk调制程序，包括载波的生成，nco的设置(FPGA-based fsk modulation procedures, including carrier generation, nco settings)

说明：  基于数据通路和控制器的高校简单PPM设计(PPM design based on datapath and controller)

用FPGA，基于M88E1111芯片实现的TCP/IP协议的千兆网，将协议封装成IP核(With the FPGA, the TCP/IP protocol based on the M88E1111 chip is used to encapsulate the protocol into IP core)

说明：  PF6182是一款很好的DC-DC同步降压IC。输出电压可调整，电流达2A。非常好用(PF6182 is a good DC-DC synchronous buck IC. Adjustable output voltage and current up to 2A. Very easy to use)

单相的主动式电压质量控制器 对电压跌落进行了补偿(single-phase AVQR for power quility improvement)

完整的verilog编写的源代码，根据实际所用的器件，修改相关参数，就可实现VGA的驱动。

自己编写的C++的类的测试程序，有详细的注注释，对初学者有很大帮助！！！(The own written C++ class test program, detailed annotation of Note of great help for beginners! ! !)

writing testbench in system verilog

说明：  XC7A35TCSG324-1的Verilog频率计程序，支持十分频，支持切换内外信号输入(Verilog frequency meter program of xc7a35tcsg324-1 supports decadal frequency division and switching internal and external signal input)

实现FPGA与PC通信的USB2.0接口,采用verilog语言实现(Implementation of FPGA and PC communication USB2.0 interface, using Verilog language to achieve)
