1984北方民族大学本科毕业论文（设计）题目：基于FPGA的查表式运算器的设计与仿真院（系）名称：电气信息工程学院学生姓名：黄斯洲学号：20130575专电子信息工程指导教师姓名：张广忠论文提交时间：北方民族大学教务处制摘要随着我国的经济的发展，人们要求计算的方法更好简单和方便，尤其是在计算这个方面，所以对于运算器的设计是非常的重要的，所以为了更好的设计该设计采用了现场可编程逻辑器件FPGA设计，并基于硬件描述语言VHDL在Altera公司的Quartus II软件上实现仿真。系统由计算部分、存储部分、显示部分和输入部分四个部分组成，计算部分为加法器、减法器、乘法器和除法器，存储部分需要3个存储器来实现：内部累加器(acc)、输入寄存器(reg)以及结果暂存器(ans)。显示部分由四个七段译码管组成，分别来显示输入数字，输入部分采用外接键盘，由0一9十个数字按键，加减乘除四个运算符按键，一个等号按键和一个清零按键组成的。通过外部的按键可以完成四位数之内的‘加’、‘减’、‘乘’、‘除’四种功能运算，其结构简单，易于实现。AbstractThis article describes the design of a simple calculator,the designuses Field Programmable Gate Array FPGA based on VHDL hardware descriptionlanguage to design and Altera's Quartus II in software for emulation.Thissystem is componentted by the calculation section,storage section,display andinput section of the four parts,the computing part include adder,subtractor,multiplier and divider,Storage part needs three memory to help achieved:internal accumulator (acc),input register (reg)as well as the results ofregisters (ans).Display part is made up three decoder of 7 sections,respectively to show the number of input.Input part has ten number keys,from0 -9,also has addition and subtraction and multiplication and divisionarithmetic operator keys,a button and of equal sign and the clear key.Buttonscan be done through external within the four-digit'add','subtract','multiple',divede'the four kinds of functional operations,its structure is simple andeasy to implement.Key words:FPGA;VHDL;calclute
