你好,关于912,2016年计算机组成原理的第一道流水线大题,三个寄存器的位置摆放有点疑问,希望能请教一下,具体如下:
按照这里的解答,让流水线时间尽可能均衡,所以寄存器放置在了A,B,D之后,但如果这样的话,
流水线的延迟(算上寄存器延迟)第二段只需要30ps,而第三段却需要60ps,也就是说第二段处理完了,第三段还在处理中,之后第二段的数据流入第三段中将会导致错误(不知道这么理解对不对),所以个人觉得这里应该是要确保三个寄存器插入之后,确保前一段的延迟不小于后一段的延迟,从而保证不会发生冲突。
所以这样的话,虽然题目不全BD的延迟不知道,但基本可以推断出,B+D=35ps,如果B延迟=30ps,D延迟=5ps的话,那么BC之间放一个,CD之间放一下,EF之间放一下,刚刚好满足要求,而且答案唯一
不知道说的对不对,请大佬指教...

因而每个进程的页表大小为$2^{16}\times 16b=32KB$。

这个计算应该是128KB吧
很多资料都失效了。。。
Hello,senior schoolmates of Tsinghua University.
I have a great honor to write this issue for you. First, let me give you a self introduction.
I am a candidate for the post-graduate entrance examination of 2022. Now I'm preparing for the exam, and I use this repository to help my review. As we all know, GitHub CAN NOT be visited at all locations of Mainland of China(Because of the GFW...), so I suggest that you could transfer the repository to the Giteehttps://www.gitee.com, a Git platform that be developed by Chinese company.
I know the action may spend lots of time, but I think we should consider it through long-term visions. First, the repository is used to help students at Mainland of China, so the way to develop it with GitHub(over the China) is not the best choice.(BaiduNetDisk needs cost some money, so it isn't a wise choice, too.)
In addition, achieve the self-development of IT as soon as possible is a more and more important thing, so please consider this suggestion cautiously.
Best wishes!
尝试了梯子之后clone也下不下来,码云因为项目太大也没法转运,直接梯子下载zip每次都是9个G左右就失败还没有断点续传,有没有其他下载方式能下载呢?
