What is the role of an ALU?

What is the role of an ALU?

The ALU has two main functions: It performs arithmetic and logical operations (decisions). The ALU is where calculations are done and where decisions are made. It acts as a gateway between primary memory and secondary storage .

What is the purpose of CU ALU and registers in CPU?

The processor’s core elements are an “Arithmetic and logic unit “(ALU) along with “Register Set”, and then a “control unit (CU)”. The ALU operates the real data analysis or computing. The “control unit” governs data and instructions navigate within the processor and handles ALU operation.

Which two important tasks is the CPU responsible for?

The CPU performs basic arithmetic, logic, controlling, and input/output (I/O) operations specified by the instructions in the program. This contrasts with external components such as main memory and I/O circuitry, and specialized processors such as graphics processing units (GPUs).

What is CU give full form and explain work of the CU in one line?

Answer: 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.

What are the functions of CU?

The control unit of the central processing unit regulates and integrates the operations of the computer. It selects and retrieves instructions from the main memory in proper sequence and interprets them so as to activate the other functional elements of the system at the appropriate moment…

What are the four basic functions implemented by a CPU?

Similarly, in a computer, the CPU controls all the important functions like Input, Processing, Data storage, Output. That is why the CPU is called the brain of the computer.

What is the main task of a CPU?

A central processing unit (CPU) is the electronic circuitry within a computer that carries out the instructions of a computer program by performing the basic arithmetic, logical, control and input/output (I/O) operations specified by the instructions.

What is the main function of CU and ALU in computer operation?

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 is the work of a CU?

The control unit (CU) is a component of a computer’s central processing unit (CPU) that directs the operation of the processor. It directs the flow of data between the CPU and the other devices.

What are the activities of a computer?

Basic computer actions

• Input.
• Output.
• Arithmetic.
• Assignment.
• Comparison.
• Selection.
• Repetition.
• Sub-Process.

What’s the difference between the ALU and the cu?

ALU is the circuit component of the CPU that deals with the mathematical and logical operations. CU is the circuit component of the CPU that instructs and directs the ALU and other computer components.

What are the characteristics of the Cu or control unit?

The characteristics of the CU or control unit are as follows: – This part of the of the CPU is the one that is in charge of all the operations being carried out. – It is responsible to direct the system to execute instructions. – It helps in communication between the memory and the arithmetic logical unit.

What is Cu and what does it do?

CU deals with the direction of all the tasks and operations performed by CPU. It coordinates and monitor the functionality of components and track the flow of data between the hardware components and the software.

What does an ALU do in a CPU?

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.
