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。

However, fancier processors, like those in your laptop or smartphone, have arithmetic units with dedicated circuits for multiplication.

然而，更高级的处理器，如笔记本电脑或智能手机中的处理器，具有带专用乘法电路的算术单元。
