基于FPGA 以太网Verilog代码

rc6 algorithm designed based on verilog and is verified

数字系统设计的入门书，教你如何学会用verilog语言实现各种数字逻辑功能，例程经典易懂(xiawenyu verilog)

Verilog RS232代码， 分为三个模块，时钟产生模块，发送数据模块，接收数据模块。 整个工程的功能是，你从串口上位机发送什么数据，串口就将该数据重新发送回上位机

QPSK调制的载波频偏估计，是一个可以调用的函数。接收端进行了一系列的处理。经典的Kay法(QPSK-carrier frequence offset estimation_ kay )

非常需要的可以下载看看,适合初学者学习,好的算法和程序(Very need to download to see, suitable for beginners to learn, good algorithm and program.)

本设计是基于FPGA的一个FIR低通滤波器设计，要求使用Verilog语言编写滤波器模块，通过编译和综合，并通过Matlab和modelsim联合仿真验证设计结果。(This design is a FIR low-pass filter design based on FPGA, use Verilog to program filter module, and joint simulation by Matlab and modelsim to validate the design results.)

design and implement a digital system on the Altera NIOS board which will read an analogue input using MicroChip’s SPI MCP3202 12-Bit A/D converter. The 8 most significant bits of the converted data will be displayed on two seven segments of the NIOS development board. The sampling frequency is 20kHZ. Use a potentiometer.(design and implement a digital system on the Altera NIOS board which will read an analogue input using MicroChip' s SPI MCP3202 12-Bit A/D converter.

AD9850 VERILOG代码 硬件验证过，可以使用。

说明：  基於空間向量調變的開關法，在於載波做比較切出方波再送至開關讓馬達啟動(Based on the switching method of space vector modulation, the square wave is cut out for carrier comparison and sent to the switch to start the moto)
