The ALU is the mathematical brain of a computer.

ALU 是计算机的数学大脑。

Basically, the operation code tells the ALU what operation to perform.

基本上，操作代码告诉 ALU 执行什么操作。

We’re going to use this ALU when we construct our CPU two episodes from now.

从现在起两集构建 CPU 时，我们将使用这个 ALU。

INTRO An ALU is really two units in one -- there’s an arithmetic unit and a logic unit.

简介 一个 ALU 实际上是两个单元合二为一——有一个算术单元和一个逻辑单元。

ALUs also output a series of Flags, which are 1-bit outputs for particular states and statuses.

ALU 还输出一系列 Flags，这些 Flags 是特定状态和状态的 1 位输出。

This is perhaps the most famous ALU ever, the Intel 74181.

这可能是有史以来最著名的 ALU，Intel 74181。

When you understand an ALU’s design and function, you’ll understand a fundamental part of modern computers.

了解 ALU 的设计和功能后，您就会了解现代计算机的基本组成部分。

These operations are handled by a computer’s Arithmetic and Logic Unit, but most people call it by its street name: the ALU.

这些操作由计算机的算术和逻辑单元处理，但大多数人都直呼其名：ALU。

Which brings us back to that ALU you admired so much at the beginning of the episode.

这让我们回到了剧集开始时您非常钦佩的那个 ALU。

Our 8-bit ALU has two inputs, A and B, each with 8 bits.

我们的 8 位 ALU 有两个输入，A 和 B，每个输入有 8 位。
