使用VHDL代码的FIR滤波器的设计

fpga实现ＣＡＮ总线控制器源码,每个项目都有说明文件，介绍使用方法。-fpga CAN Bus Controller source, each with explanatory documents on the use of methods.

用verilog实现endat2_1驱动,并用signalTap捕捉信号。(Using verilog achieve endat2_1 drive and use signalTap capture signal.)

DDR2-400样例源代码，用于Xilinx Spartan 3A/3AN Starter Kit(DDR2-400 sample source code for Xilinx Spartan 3A/3AN Starter Kit)

这是二十四进制计数器的源程序，有需要的同学可以参照一下！(This is 24 hexadecimal counter source, needy students can refer to you!)

（1）距离算法研究和设计； （2）采用FPGA/CPLD实现。 -(1) distance algorithm and design (2) using FPGA/CPLD implementation.

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)

VHDL实现PI调节的算法。内部使用整数计算，避开了浮点数的运算。仿真结果正确-VHDL realize PI regulator algorithm. Internal use integer calculations to avoid the floating point arithmetic. The simulation results correctly

SAP-1硬件描述语言（使用Verilog语言）

这是很全的标准库啊，不是1164.vhd，都是一些加，乘，除，平方等操作的包来的．-This is the standard for the whole ah, not 1164.vhd are some increases, multiplication, addition, operational square packages to come.
