Technical details and manufacturing context for Arithmetic Logic Unit

Definition
The Arithmetic Logic Unit (ALU) is a critical component of a central processing unit (CPU) that executes all arithmetic calculations (addition, subtraction, multiplication, division) and logical operations (AND, OR, NOT, XOR, bit shifts) as directed by the processor's instructions. It is the primary computational engine of the CPU, handling data from registers and memory to produce results that are stored back in registers or memory.
Working Principle
The ALU operates by receiving one or more operands (binary numbers) from CPU registers via input buses. Based on the operation code (opcode) from the control unit, it selects and activates the appropriate internal circuitry (e.g., adder, shifter, logic gates) to perform the specified arithmetic or logic function. The result is output, along with status flags (like zero, carry, overflow) that indicate the outcome's properties, which are used for conditional branching and program flow control.
