LCD 因其轻薄短小,低功耗,无辐射,平面 直角显示,以及影像稳定等特点,当今应用非常 广泛。CPLD(复杂可编程逻辑器件) 是一种具有 丰富可编程...

基于altera系列芯片lvds接口的fpga设计 verilog源码-Series altera-based chip interface lvds source fpga design verilog

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)

这个是讲pll的具体用法的,一般在fpga设计中都会用到 他,这个是lattice的xp2的pll的介绍,不过,fpga 都是相通的其他两家也差不多(Pll say this is the specific usage, the general design in the FPGA will use him, this is the lattice of the pll of xp2 introduction, however, fpga are connected to other two similar)

利用verlilog hdl语言编程，完成了8051内核，非常值得学习硬件描述语言的人看看！-Verlilog hdl programming language to use to complete the 8051 core, very much worth learning hardware description language of the people to see!

2FSK的matlab仿真，叠加了高斯白噪声(2FSK matlab simulation, superimposed on a Gaussian white noise)

这段代码是用来实现二维高斯滤波器的。

实现了三种乘法器，可以进行性能比较，比较有较之-multi

基于FPGA的1553b接口设计详细设计论文(1553B design based on FPGA)

说明：  详细介绍了如何使用ModelSim进行仿真.(it will teach you how to use the ModelSim to simulink.)

能实现数字钟中时间的显示，并可对小时，分钟，秒进行调整-Can realize the time digital clock display, and on the hours, minutes, seconds to adjust
