Fixed point computer arithmetic
WebThe Arithmetic Logic Unit (ALU) is the heart of any CPU. An ALU performs three kinds of operations, i.e. Arithmetic operations such as Addition/Subtraction, Logical operations such as AND, OR, etc. and Data movement operations such as Load and Store ALU derives its name because it performs arithmetic and logical operations.
