combinational digital circuit that performs arithmetic and bitwise operations on binary-coded integer numbers
An arithmetic logic unit is a computer circuit that performs basic math and logical operations on numbers represented in binary code. It matters because it's a fundamental building block that enables processors to do calculations and make decisions, which are essential for all computing tasks.

算术逻辑单元（英语：Arithmetic logic unit，简称：ALU）是一种可对二进制整数执行算术运算或位运算的组合逻辑数字电路。ALU 与浮点数运算单元（FPU）不同，后者仅对浮点数进行操作。ALU 是许多类型的计算电路的基本部件，这些计算电路包括计算机的中央处理单元（CPU）、浮点处理单元（FPU）和图形处理单元（GPU）。单个CPU、FPU 或 GPU 可能包含多个 ALU。 ALU 的输入包括需要运算的数据（也称为运算数）和表明了运算操作类型的指令码。ALU 的输出是其执行运算的结果。在许多的设计中，ALU 还带有状态输入或输出，可将其之前操作或当前操作的信息在 ALU 和外部状态寄存器间传递。
