So that’s a high level overview of what makes up an ALU. We even built several of the main components from scratch, like our ripple adder.

所以这是对 ALU 组成的高级概述。我们甚至从头开始构建了几个主要组件，例如我们的纹波加法器。

INTRO All of the logic circuits we've discussed so far go in one direction - always flowing forward - like our 8-bit ripple adder from last episode.

简介 到目前为止我们讨论的所有逻辑电路都朝着一个方向发展——总是向前流动——就像我们上一集中的 8 位纹波加法器一样。
