MICROPROCESSOR AND MICROCONTROLLER

Detailed explanation-1: -The control unit (CU) is a component of the 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.

Detailed explanation-2: -A control unit, or CU, is circuitry within a computer’s processor that directs operations. It instructs the memory, logic unit, and both output and input devices of the computer on how to respond to the program’s instructions.

Detailed explanation-3: -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.

Detailed explanation-4: -It consists of an arithmetic and logic unit (ALU), a control unit, and various registers. The CPU is often simply referred to as the processor. The ALU performs arithmetic operations, logic operations, and related operations, according to the program instructions.

Detailed explanation-5: -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. Modern CPUs contain very powerful and complex ALUs. In addition to ALUs, modern CPUs contain a control unit (CU).
