计算机体系结构实验-单功能流水线调度机构模拟

1、精选优质文档-倾情为你奉上CENTRAL SOUTH UNIVERSITY 计算机体系结构实验报告题 目 单功能流水线调度机构模拟 一、实验目的结合数据结构的相关知识,编写流水线调度模拟程序。二、实验环境Eclipse IDE for Java Developers（Version: Kepler Release）Win7三、实验内容程序通过模拟单功能流水线调度过程，掌握流水线技术，学会计算流水线的吞吐率、加速比、效率。 1 流水线的表示法有三种：连接图、时空图、预约表。对于线性流水线，主要考虑前二种。2 流水线的主要特点：在流水线的每一个功能部件的后面都要有一个缓冲器，称为锁存器、闸门寄存器

2、等，它的作用是保存本流水段的执行结果。各流水段的时间应尽量相等，否则回引起阻塞、断流等。只有连续提供同类任务才能充分发挥流水线的效率。在流水线的每一个流水线段中都要设置一个流水锁存器。流水线需要有“装入时间”和“排空时间”。只有流水线完全充满时，整个流水线的效率才能得到充分发挥。四、关键代码/构筑主窗体大小颜色：public void lauchFrame() this.setLayout(null);this.setBounds(100, 100, 600, 500);this.setBackground(Color.cyan);this.setVisible(true);/当输入为3时，显
