计算机中，解释并执行指令的一种功能单元。注：处理器至少包含有一个指令控制器和一个算术与逻辑运算器。

In a computer, a functional unit that interprets and executes instructions. Note: a processor consists of at least an instruction control unit and an arithmetic and logic unit.

另外，精心设计了微控制器的核心部件算术逻辑单元。

Additionally, we exactly designed the central process department: Arithmetic Logic Unit.

算术逻辑运算单元（ALU）决定着中央处理器（CPU）的性能，而加法器又决定着ALU的性能。

The arithmetic logic unit(ALU) decides the performance of the Central Processing Unit(CPU), while the adder decides that of the ALU.
