Whether at home or work, it is common for many individuals to have easy access to computers in modern day life. However, only a few people know how computers actually function. One such component that is fundamental for the operation of computers is the electronic microprocessor. This component is a small, yet powerful, circuit board that processes binary data as input commands, and works to provide an output accordingly. While the aforementioned information is not enough to understand the complexity of electronic microprocessors, in this blog, we will briefly go over what a microprocessor is and its functions.
What Is a Microprocessor?
Microprocessors are the most critical component of a computer and are commonly known as the central processing unit (CPU), processor, or logic chip that is the computer’s brain. When you switch on your computer, the microprocessor will instantly begin to function. It processes binary numbers and performs operations such as addition, subtraction, transferring between memory locations, and/or comparing two values. This programmable device incorporates all functions from CPUs onto one integrated circuit (IC) to be implemented quickly and more efficiently.
How Does a Microprocessor Work?
Microprocessors are tiny pieces of silicon that process data and provide outputs based on instructions stored in the computer’s memory. The inputs are the binary data that microprocessors process depending on the command being sent, and then provide a result as per the instructions stored in the memory.
The input is processed using an ALU (arithmetic & logical unit) which controls logic for management purposes, and a register array that acts like a temporary fast access storage location. It enables you to make changes quickly without going over your program's code again. A control unit manages the flow of instructions and data through the system.
Benefits of a Microprocessor
Microprocessors are so versatile that they are now considered the backbone of modern technology, powering everything from smartphones to household appliances, cars, and more. The following are some of the few advantages and reasons for such extensive use of microprocessors:
Microprocessors are the brains of our computers, allowing them to perform various tasks like text editing, multimedia display, and much more. They have changed the way we implement technology drastically with their small size, fast processing speeds, and energy efficiency, becoming a critical part of the development and standardization of technology.
