利用扫描加记数程序实现百进制,适合VHDL的初学者使用.

键盘计算器，可实现加减乘数运算 基于fpga nios2(Keyboard, calculator, addition and subtraction can be realized based on fpga nios2 multiplier operator)

假设每个从设备中有可访问APB寄存器16个，位宽均为32比特，16个寄存器的访问地址计算方式为 基址 +　寄存器编号左移２位（byte 偏移）(Assuming that there are 16 accessible APB registers in each slave device, the bit width is 32 bits, and the access address of 16 registers is calculated by base address + register number left shift 2 bits (byte offset).)

EDA中常用模块VHDL程序，不同时基的计数器由同一个外部是中输入时必备的分频函数。分频器FENPIN1/2/3(50分频=1HZ，25分频=2HZ，10分频=5HZ。稍微改变程序即可实现)-EDA VHDL modules commonly used procedure, the time- with a counter by the external input is required when the sub-frequency functions. Frequency Divider FENPIN1/2/3 (50 1HZ frequency = 25 = 2HZ-frequency, frequency = 10 points Stripper. A slight change in procedure can be realized)

本程序是用verilog 编写的模块，用来在lcd1602上显示用tlc549采样的电压值(This program is written in verilog module, used in lcd1602 display with tlc549 sampled voltage value)

数字电子钟设计完整设计，包括原理介绍，程序设计，波形仿真-Design a complete digital electronic clock design, including the principle of introduction, program design, waveform simulation

设计的结构是纹波进位加法器，但执行的操作是加法和减法，两种操作都是32位的，具体取决于控制信号。如果控制信号为“1”，则选择减法，然后选择“0”，然后选择加法

说明：  用verilog语言开发俄罗斯方块小游戏(Developing Tetris game with Verilog language)

用VHDL写的计算器，实现加减功能以及ＶＧＡ显示功能，适合VHDL初学者使用。-VHDL write calculators, Modified functions and achieve VGA display, VHDL for beginners.
