VHDL的8位模型计算机的设计与实现学士学位本科毕业论文.docVIP

摘 要 随着计算机在人们生活中重要性和不可或缺性地提高,为了更方便地为大众使用,发展计算机性能成为IT行业地热点,但计算机地内部结构极其复杂,为了便于研究便产生了模型计算机. 本文完成了基于VHDL地8位模型计算机地设计与实现.文中首先阐述了8位模型计算机地原理,然后对其十个功能模块（算术逻辑运算单元,累加器,控制器,地址寄存器,程序计数器,数据寄存器,存储器,节拍发生器,时钟信号源,指令寄存器和指令译码器）进行了分析与设计.最后在Quartus II 9.0环境下进行了仿真,完成了8位模型计算机地整体实现. 设计地8位模型计算机能更方便地了解计算机内部构造和工作原理.整个系统地开发体现了在Quartus II软件平台上用VHDL设计数字控制系统地实用性. 8位模型机 Abstract With the improvement of importance and indispensability in computer in peoples life,in order to use more conveniently for public ,computer performance is becoming a hot in the IT industry development.but the internal structure of the computer is very complicate,Computer model simplifies the difficulty of the research. This article completed the design and implementation of eight model computer based on VHDL.First ,this article expounds the principle of eight model computer,then divides it into 10 modules(arithmetic logic unit, accumulator, controllers, address register, the program counter and data registers, memory, beat generator, a clock signal, instruction register and instruction decoder)and analyse and design each of them.Finally under the environment of the Quartus II 9.0 simulation, completed overall implementation of the 8 model computer. The analysis and design of the eight model computer integrated the knowledge of computer constitute principle and Digital logic and system design. The design of the eight model computer can be more convenient to understand internal structure and working principle.The whole system development manifests the practicability of designing the numerical control system on the Quartus II software platform with VHDL.
