【51】PCIe简介

小鱼儿 2023-07-06 08:46 9阅读 0赞

贴一下之前写的一个PCIe简介的PPT，都是些PCIe领域的基本概念。现在觉得写这样的PPT给大家讲挺没有意思的，但是很多人都喜欢听这种形式。怎么说呢，如果别人给你说一下，你就全懂了，然后可以工程化了，那只能证明他说的东西本身就没啥技术含量。有技术含量的东西就是我告诉你方案，你依然做不出产品。比如原子弹，全世界读过高中物理的都知道把铀235浓缩到一定程度，然后压缩到临爆点就是原子弹，但是世界上独立发展出原子弹的只有中美俄，其他国家都是源自于这三家的技术，这就是魔鬼都在细节中。  
   纸上得来终觉浅，绝知此事要躬行。别人只能给你的思路，成事还看个人努力。大部分人都是看了别人思路，晚上回家想想，感觉条条大道通罗马，第二天起来依旧磨豆腐。为啥呢？别人的始终是别人的，你能按照自己思路写下来，哪怕和别人的一模一样，那也是你自己的，别把自己读成人形书柜。读书破万卷，重要的从来不在万卷，而在于“破”，破一卷胜过读万卷。  
   PPT中的很多图片都是来自PCIeBuster、SSD fans，其实市面上大部分讲PCIe的资料的图（包括SSD fans）都来源于PCIe architecture这本英文宝典，我是懒得在里面翻了，从PCIeBuster、SSD fans拿了一些图。PCIeBuster不用担心原创版权问题，因为有些文章本身就是我写的。
