1 - About

The ALU is a component of a CPU.

It is a device that executes all arithmetic and logical operations.

In most arithmetic logic unit (ALU) hardware, we find a fixed-precision arithmetic found , which typically offers between 8 and 64 bits of precision (Arbitrary-precision_arithmetic)


3 - Operations

  • arithmetic operations, or mathematical calculations: addition, subtraction, multiplication, and division.
  • logical operations and comparison. The unit can compare numbers, letters, or special characters.
