this code for integrator for 8 bit signal

xilinx SP6系列的3-8译码器实现(Implementation of Xilinx SP6 Series 3-8 Decoder)

是一个LED点阵显示屏的原理图，非常详细，适合开发者学习(LED dot matrix display is a schematic diagram is very detailed, for developers to learn)

用verilog编写的信号调制解调程序，包括ask,fsk,qpsk的fpga实现(Prepared using verilog signal modulation and demodulation process, including ask, fsk, qpsk of fpga implementation)

16位元浮点数CPU,可作运算,以VHDL编写-16-bit floating point CPU, can be used for computing in order to prepare VHDL

Verilog数字系统设计教程【夏宇闻】原书第十章：IIC总线接口模块设计代码包-verilog program for iic bus design. the pakege includes iic protocl master program and behavel slavle program, even includes testbench and data bat files.

用verilog写的各种实用的分频器，很好的参考例子。-Using Verilog to write a variety of practical divider, a good reference example.

  基于FPGA(Field-Programmable Gate Array)的OFDM(Orthogonal Frequency Division Multiplexing)信号传输系统VHDL源码 use IEEE.std_logic_unsigned.all; package outconverter is constant stage : natural := 3; constant FFTDELAY:integer:=13+2*STAGE; constant FACTORDELAY:integer:=6; constant OUTDELAY:integer:=9; function counter2addr( counter : std_logic_vector; mask1:std_logic_vector; mask2:std_logic_vector ) return std_logic_vector; function outcounter2addr(counter : std_logic_vector) return std_logic_vector; end outconverter; package body outconverter is function counter2addr( counter : std_logic_vector; mask1:std_logic_vector; mask2:std_logic_vector ) return std_logic_vector is variable result :std_logic_vector(counter"range); begin for n in mask1"range loop if mask1(n)="1" then result( 2*n+1 downto 2*n ):=counter( 1 downto 0 ); elsif mask2(n)="1" and n/=STAGE-1

进阶实验之SRAM测试，由verilog编写，可直接对sram进行存写(Advanced SRAM test experiments, written by the verilog, can be stored directly on the sram write)
