ALU and CU are the heart of the CPU. ALU is the Arithmetic and Logic Unit which performs all the arithmetic and logical operations such as addition, subtraction, logical AND, OR etc. CU is the Control Unit. It decodes the instructions, and controls all the other internal components of the CPU to make it work.
Similarly, what is the definition of Alu?
Abbreviation of arithmetic logic unit, the part of a computer that performs all arithmetic computations, such as addition and multiplication, and all comparison operations. The ALU is one component of the CPU(central processing unit).
Is the ALU A register?
Registers and the ALU. The arithmetic/logic unit (ALU) of a processor performs integer arithmetic and logical operations. For example, one of its operations is to add two 32-bit integers. The second operand (often in a register).
What are the main function of the control unit?
The control unit (CU) is a component of a computer's central processing unit (CPU) that directs the operation of the processor. It tells the computer's memory, arithmetic/logic unit and input and output devices how to respond to a program's instructions.
