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.
What is the difference between working of ALU and CU?
ALU vs CU. Summary: Difference Between ALU and CU is that arithmetic logic unit, another component of the processor, performs arithmetic, comparison, and other operations. While control unit is the component of the processor that directs and coordinates most of the operations in the computer.
How does the ALU and the accumulator work together?
The accumulator can hold one of the two operands during any ALU operation. If we want to add two bytes together, this would just be an example here; one byte would go to the accumulator, and the other in memory or general purpose register. When executed the two numbers serve as the input to the ALU.
What are the functions of ALU?
An arithmetic logic unit (ALU) is a digital circuit used to perform arithmetic and logic operations. It represents the fundamental building block of the central processing unit (CPU) of a computer.
Which unit does Alu work in coordination with?
ALU is stands for arithmetic and logical unit which performs all arithmetic operations like addition, subtraction, division and multiplication and logical operations of the computer system. It works the coordination of control unit and memory unit. It is the building block of CPU.
What is the meaning of ALU and CU?
ALU. CU. Definition. ALU (Arithmetic Logical Unit) is a circuit component of CPU that deals with the mathematical calculations, data processing and deducting all the logical conclusions and outputs. CU (Control Unit) is one of the two main components of the CPU.
What is function of CU?
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 and logic unit and input and output devices how to respond to the instructions that have been sent to the processor.
