The Arithmetic Logic Unit (ALU) is a fundamental component of the CPU, executing arithmetic and logical operations crucial for computer functionality. It works in tandem with the Control Unit, which coordinates CPU activities. The ALU's design impacts computational speed and efficiency, with considerations for performance, power efficiency, and space on the silicon chip. Understanding the ALU's role and design is key to advancements in computer architecture.
