Arithmetic Logic Unit
ConceptIn the provided Y86-64 microprocessor evidence, the arithmetic logic unit (ALU) is an execute-stage functional block that operates on register values, immediate instruction data, and numeric constants. It can perform addition or the arithmetic/logical operation selected by an instruction, producing an ALU result used by later memory and write-back activity.

Overview
An Arithmetic Logic Unit (ALU) is identified in the provided Y86-64 processor material as the hardware block responsible for arithmetic and logical operations. In the SEQ sequential reference implementation, the ALU is part of the execute-stage data path and is controlled along with other processor blocks whose detailed functionality is described in HCL, a language for describing control logic.
