Explore the essential role of microprocessors as the CPU "brain" of devices, their functions, types, applications, and future innovations.
What is microprocessor and how it works?
A microprocessor is a central processing unit (CPU) that serves as the "brain" of a computer or electronic device.
It is a highly integrated circuit that performs various processing tasks, including executing instructions,
performing calculations, and managing data. Microprocessors are essential components in a wide range of devices,
from computers and smartphones to appliances and automotive systems. Table of Contents How a Microprocessor Works Key Components of a Microprocessor Types of Microprocessors Applications of Microprocessors The Future of Microprocessors Frequently Asked Questions 1. How a Microprocessor Works
The operation of a microprocessor is based on a cycle called the "fetch-decode-execute" cycle:
Fetch: The microprocessor fetches the next instruction from memory. The memory address of the instruction is determined by the program counter (PC), a special register that keeps track of the current instruction. Decode: The fetched instru…
