What is Microprocessor, Definitions & Application

Authored By: Ankita Prajapati

A microprocessor is an integrated circuit (IC) that contains all the components of a computer‘s Central Processing Unit (CPU) on a single chip. It is considered thebrain of the computer, responsible for carrying out all the instructions of a program. It is a highly versatile and efficient device that is used in almost all types of electronic devices from microwaves to iPhones.

The microprocessor was invented in 1971 by Intel Corporation. It was the first singlechip microprocessor, containing all the logic and memory needed for a computer. It was the first device to combine both memory and logic circuits into a single chip.

This single chip allowed for the development of the first personal computers. Since its invention, microprocessors have become increasingly powerful, faster, and more capable.

They are now capable of performing trillions of calculations per second. They are used in a wide variety of applications, including digital signal processing, video processing, audio processing, network communication, control systems, and scientific computing.

Microprocessors are designed and manufactured using advanced semiconductor technology. They usually include a core processor, memory, and support logic.

The core processor is responsible for executing instructions and performing calculations. Memory stores data and instructions, while support logic controls the overall operation of the chip.

Today, microprocessors are used in a variety of devices including cell phones, laptops, tablets, gaming consoles, and many other electronic devices.

They are also used in industrial applications for controlling robotic arms, monitoring sensors, and other industrial automation tasks.

Microprocessors are the foundation of modern computing and are essential for the development of new technologies. They will continue to play an important role in the future of computing, as they become more powerful and more efficient.


  1. A microprocessor is a computer processor that incorporates the functions of a central processing unit on a single integrated circuit (IC), or at most a few integrated circuits.
  2. It is a multipurpose, programmable device that accepts digital data as input, processes it according to instructions stored in its memory, and provides results as output.
  3. Microprocessors contain both combinational logic and sequential digital logic. Microprocessors operate on numbers and symbols represented in the binary numeral system.
