Embedded Systems


Hearing about embedded systems may come as weird to you at first, what are they? What do they do, have I ever seen or interacted with one? The answer to some of these questions is in your pocket right now. Mobile phones, computers, tablets, digital electronic systems, laptops, and many other gadgets are designed using embedded systems, so what are they exactly?

An embedded system is basically an electronic system that combines hardware circuitry and software programming techniques together to make circuits less complicated, smaller and lighter. All electronic systems are made up of hardware circuitry and embedded systems are no different, they have a power supply, central processing units, timers, output circuits, memory devices, communication ports and some other components that relate to the application of the embedded system.

Embedded systems come in one of two configurations, they are either microcontrollers based, or the microprocessors based, and in both, there is an integrated circuit at the heart of the product that is responsible for doing the computations for real-time operations. Both kinds of hardware configurations look the same, but as microprocessors only implement a central processing unit and therefore needing other components to function properly such as memory chips, and this is not the case with microcontrollers as they are designed as a self-contained system.
