OFDM系统中的相位跟踪模块（Phase_Tracking）的FPGA实现-Phase_Tracking in OFDM sysytems

基于Basys3的数字钟实例，主要用于Basys3、vivado开发环境入门。源码使用VerilogHDL(Based on digital clock instance Basys3, mainly for Basys3, vivado development environment started. Use Code VerilogHDL)

用verilog语言编写的4位算术逻辑单元ALU,功能参考74181，包含.v文件以及测试用.vwf文件(Verilog languages with four arithmetic logic unit ALU, functional reference to 74,181, including. V documents and testing. Vwf document)

This tutorial presents an introduction to Altera’s Nios R II processor, which is a soft processor that can be in- stantiated on an Altera FPGA device. It describes the basic architecture of Nios II and its instruction set. The NiosII processor and its associated memory and peripheral components are easily instantiated by using Altera’s SOPCBuilder in conjuction with the Quartus R II software.

调制信号后4倍内插的verilog代码，用于基带成型滤波器输入数据(4 times after modulation signal interpolation verilog code, used to baseband shaping filter input data)

D-flip flop vhdl implement code

说明：  基于OV7670采集，SDRAM缓存，sobel处理，VGA显示的工程，内有全部代码，基于QUARTUS开发板实现。 FPGA 边缘检测(Based on OV7670 acquisition, SDRAM cache, sobel processing, VGA display project, with all the code, based on QUARTUS development board. FPGA edge detection)

Very suitable for the study using computer vision, Analysis of the signal time domain, frequency domain, cepstrum, cyclic spectrum, etc. The performance of the program has reached a high level.

递增方式在4位数码管上向上计数显示从0000-0001->0002……..9999….0000….0001…. -- 利用CPLD设计了一个4位十进制计数器，并用数码管显示当前计数值-Incremental approach in the four counts upward digital tube display from 0000-0001-
