超标量流水线多发射策略教学要点与教学方法探讨

Discussion of Teaching Points and Methods for Multiple Issue Strategy of Superscalar Pipeline

计算机系统结构课程中超标量流水线的多发射策略是教学的重点和难点,文章介绍在讲授多发射策略时遇到的指令发射过程和数据写回过程方面的问题,提出在教材的基础上引入了带有先行窗口的双发射超标量流水线、重排序缓冲器和调度栈等实例,既充实了超标量流水线的内容,又有效地化解了教学难点。

In computer architecture course, the multiple issue strategies of superscalar pipeline are important and difficulty content for students. Some problems in instruction issue process and data write back when teaching multiple issue strategies are introduced in this paper. Some examples on the basis of the textbook are introduced, such as dual issue superscalar pipeline with look-ahead window, reorder-buffer, and dispatch stack in class. Using this way, not only enrich the content of superscalar pipelining, but also decrease difficulties efficiently.
