基于FPGA的等精度计频器

BPSK调制器verilog代码。这是bpsk调制的精确表示；

使用metlab生产正弦波和三角波的采样值，供vhdl等语言调用来产生波形(use metlab production sine wave and triangular wave of sampling, for languages such as call vhdl to generate waveforms)

该程序使用Verilog语言产生LFM信号(The program uses Verilog language to generate LFM signals.)

说明：  verilog编码器、计数器、加法器的程序(Verilog encoder, counter, adder procedures)

华为内部资料，关于FPGA设计的详细过程介绍，很不错的。本文档从FPGA器件结构出发以速度路径延时大小和面积资源占用率为主题描述在FPGA设计过程中应当注意的问题和可以采用的设计技巧。(Huawei internal information, with regard to detailed FPGA design process of introduction, it is good. This document from the FPGA device structure in order to speed the path delay and area the size of the theme of the occupancy rate of resource description in the FPGA design process should pay attention to the problems and design techniques can be used.)

说明：  实现在屏幕上显示绿色和红色相间的水平条纹。其中，vga_640x480模块将产生行同步信号hsyn和场同步信号 vsync; vga_stripes模块将产生red、green和blue三个输出。(The horizontal stripes of green and red are displayed on the screen. Among them, vga_640x480 module will produce line synchronization signal Hsyn and field synchronization signal vsync; vga_stripes module will produce red, green and blue three outputs.)

IP 核的接口（The Avalon® Streaming (Avalon-ST) interface）的使用说明，和程序(IP core interface (The Avalon Streaming (Avalon-ST) interface) instructions for use, and procedures)

说明：  verilog 版本，Xilinx玩转USB3.0，LVDS接口(verilog version,Xilinxplay with USB3.0,LVDS)

this is the vhdl code for the arithmetic logic unit.enjoy!
