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.
What is control unit and its types?
A control unit or CU is circuitry that directs operations within a computer’s processor. It lets the computer’s logic unit, memory, as well as both input and output devices know how to respond to instructions received from a program. Examples of devices that utilize control units include CPUs and GPUs.
What is control unit design?
Control unit generates timing and control signals for the operations of the computer. The control unit communicates with ALU and main memory. It also controls the transmission between processor, memory and the various peripherals. It also instructs the ALU which operation has to be performed on data.
Is ALU A hardware?
Computer Software and Hardware – Arithmetic Logic Unit
In addition to ALUs, modern CPUs contain a control unit (CU). An ALU performs basic arithmetic, examples of arithmetic operations are addition, subtraction, multiplication, and division.
Can we call control unit the control Centre of computer system?
Answer: The Control Unit (CU) controls and guides the interpretation, flow and manipulation of all data and information. The control unit even controls the flow of data from input devices to memory and from memory to output devices.
