What is meant by control unit?
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.
What are the 3 components of CPU?
Whatever is done on our computers, such as checking emails, playing games and doing homework, the CPU has processed the data we use. The CPU is made up of three main components, the control unit , the immediate access store and the arithmetic and logic unit .
What is control unit and ALU?
An arithmetic logic unit (ALU) is a digital circuit used to perform arithmetic and logic operations. The control unit tells the ALU what operation to perform on that data, and the ALU stores the result in an output register. The control unit moves the data between these registers, the ALU, and memory.
What are the structural components of a control unit of a CPU?
The two typical components of a CPU include the following:
- The arithmetic logic unit (ALU), which performs arithmetic and logical operations.
- The control unit (CU), which extracts instructions from memory and decodes and executes them, calling on the ALU when necessary.
What are the types of control unit?
There are two types of control units: Hardwired control unit and Microprogrammable control unit.
- Hardwired Control Unit –
- Microprogrammable control unit –
What are the control unit and its functions?
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.
