用fpga驱动lcd的原代码，是用vhdl语言实现的

该源码为VHDL语言编写的分频器，在W-4b教学平台上通过验证-The VHDL source for the prescaler languages, W-4b in the teaching platform validated

说明：  国外的CIC补偿滤波器设计文件，非常有用(Abroad, CIC compensation filter design files, very useful)

网络通信中的MII接口 通常将4位nibble数据送出，此程序将4位数据组合成8位数据并行输出（8比特==1个字节）。。完全可用 同时包含84转换(The MII network interface usually sent four nibble data, this procedure will be 4-bit data into 8-bit parallel output data (8 bits == 1 byte). . Completely available at the same time contains 84 conversion)

基于FPGA的UDP硬件协议栈， 全部用SystemVerilog写的，不需CPU参与，包括独立的MAC模块。 支持外部phy的配置，支持GMII和RGMII模式。 以下是接口 input clk50, input rst_n, /////////////////////// //interface to user module input [7:0] wr_data, input wr_clk, input wr_en, output wr_full, output [7:0] rd_data, input rd_clk, input rd_en, output rd_empty, input [31:0] local_ipaddr, //FPGA ip address input [31:0] remote_ipaddr, //PC ip address input [15:0] local_port, //FPGA port number //interface to ethernet phy output mdc, inout mdio, output phy_rst_n, output is_link_up, `ifdef RGMII_IF input [3:0] rx_data, output logic [3:0] tx_data, `else input [7:0] rx_data, output logic [7:0] tx_data, `endif input rx_clk, input rx_data_valid, input gtx_clk, output logic tx_en(UDP hardware stack, written in system verilog, do nt need CPU.Projgect includes MAC Layer,support phy configuration.support gmii and rgmii mode. the interface is as the follows: input clk50, input rst_n, /////////////////////// //interface to user module input [7:0] wr_data, input wr_clk, input wr_en, output wr_full, output [7:0] rd_data, input rd_clk, input rd_en, output rd_empty, input [31:0] local_ipaddr, //FPGA ip address input [31:0] remote_ipaddr, //PC ip address input [15:0] local_port, //FPGA port number //interface to ethernet phy output mdc, inout mdio, output phy_rst_n, output is_link_up, `ifdef RGMII_IF input [3:0] rx_data, output logic [3:0] tx_data, `else input [7:0] rx_data, output logic [7:0] tx_data, `endif input rx_clk, input rx_data)

cordic算法的fpga的实现 采用altera芯片-cordic realization algorithm using fpga chip altera

书名：LDPC原理与应用。是国内第一本介绍用LDPC编、译码基本原理及应用技术的一本书。对用 vhdl 或verilog实现硬件编程LDPC的人开发无线通信是很好的资料(Title: LDPC Principles and Applications. Is the first book describes using LDPC Encoding and Decoding the basic principles and application of technology, a book. Right to use vhdl or verilog hardware programming LDPC people to achieve development of wireless communications is a very good information)
