1、华北科技学院计算机系设计性实验实验报告课程名称计算机组成原理B 实验学期 2011 至 2012 学年第一学期学生所在系部计算机学院年级 2011 专业班级学生姓名学号任课教师实验成绩计算机系制实验报告须知1、学生上交实验报告时，必须为打印稿（A4纸）。页面空间不够，可以顺延。2、学生应该填写的内容包括：封面相关栏目、实验地点、时间、目的、设备环境、内容、结果及分析等。3、教师应该填写的内容包括：实验成绩、教师评价等。4、教师根据本课程的实验指导中实验内容的要求，评定学生的设计性实验成绩；要求在该课程期末考试前将实验报告交给任课教师。设计性实验中，所涉及的

2、程序，文档等在交实验报告前，拷贝给任课教师。任课教师统一刻录成光盘，与该课程的期末考试成绩一同上交到系里存档。5、未尽事宜，请参考该课程的实验大纲和教学大纲。计算机组成原理B课程设计性实验报告开课实验室：计算机组成原理实验室 2011 年11 月 9 日实验题目指令扩展实验一、实验目的深入了解教学计算机微程序控制器的组成和设计技术，包括Am2910器件的功能与具体用法，教学计算机的总体组成和部件之间的连接方法，总之应该深入理解控制器部件的组成、设计、控制与使用等诸项知识。二、设备与环境TEC-XP+教学机，微机一台，装有Windows XP、ISPLEVER、ispVM System等软件

31、明了实验的成功，同时也验证了理论的正确性。2.下面的两张图片是SWRM指令扩充后，验证程序及实验结果的截图：（1）此张截图验证了存储器中的内容确实进入了寄存器当中：大家由下图可知，该验证程序从一2000为抵制的内存单元中开始的，R1寄存器当中存储了数据5，R0寄存器当中存储了数据2100（就是要和寄存器R1进行交换的存储器的地址），以2004为地址的内存单元的指令就是为了实现前面扩充的指令SWRM，因为其编码即为A1，要交换的寄存器级存储器的地址存在于R0和R1当中所以指令格式为A110，我们在以2100为地址的存储器当中放入了数据9876，运行万的结果如下图所示可以清楚的看到R1寄存器当中的值已经变成9876即存储单元当中的内容，说明存储器当中的数据存入寄存器成功。(2)下面这张图片验证了存储器当中的数据也确实成功的进入了以2100为地址的存储器单元当中。如上图所示，当执行显示存储器单元命令D后，显示的2100单元存储的值为0005，即为在验证程序中R1寄存器当中存入的值。上面的两张图片足以验证SWRM该条指令扩充的正确性。教师评价评定项目ABCD评定项目ABCD基本部件原理清楚操作熟练微指令设计合理解析完整微程序功能正确文字流畅验证程序运行正确报告规范其他：评价教师签名：年月日
