Real-Time Applications of Embedded Systems in Our Day to Day Life
The world is full of embedded systems. Ever since microcontrollers were developed, several embedded system applications came into existence. They still have a lot of significance in our day to day life.
Where are Embedded Systems Used?
Get up and take a look around; starting from consumer electronics (such as digital cameras, mobile phones, and DVD players) to high-end systems (such as flight controllers and missile guidance systems) we are surrounded by sophisticated pieces of embedded systems.
This technology has become an integral part of our life and it will continue to be the same for the future.
Role of Embedded Systems
An best embedded training institute in rajajinagar with placement is designed to perform one single task. They are application oriented. If it performs a multiple number of tasks, all will be intended to works towards one single task.
For example, to get wireless connectivity in our smartphones, laptops, tablets, and desktops, you need a wireless router. This router uses the signals from a cable and transmits them wirelessly to the devices. It also collects the data from those devices and sends it through the cable.
There are many tasks performed by the embedded system. Some of them include assigning a dynamic IP address, data encryption and security, and so on. No matter what tasks it performs, the ultimate goal is to provide wireless internet connectivity to the devices.
Real Time Embedded Systems

is a computer system that is bound by time constraints. These constraints include the response time (time taken to respond to an event), start time (time at which the response starts), and end time (time at which the respond ends).
Characteristics of Real-Time System
It has two important characteristics, such as:
- It must generate the right computational responses at a certain event; and
- Those ‘responses’ should comply with time constraints. In other words, the responses should come within a predefined time.
Types of Real-Time Systems
Based on their timing constraints, such systems are classified into two types, such as Hard Real-Time Systems and Soft Real-Time Systems.
Hard real time systems maintain flexibility regarding time constraints. If they fail to achieve that, it would end up with dire consequences. This classification of systems is designed to generate accurate responses to events within a specified period of time. If any of them is failed to deliver, it would result in catastrophic results.
The ‘soft real-time systems’ on the other hand produce responses within the specified period of time with a little relaxation or flexibility on the deadline. In this category, if the response is not achieved in time, the results will not be catastrophic but will definitely cost you a delay in the transmission process.
Embedded systems like GPS, latest Smart TVs, space exploration vehicles, and automobiles rule our everyday life. This growing use of embedded systems has opened new ways for research in this field. Various courses are being introduced to colleges and various certification courses are offered to working professionals and enthusiasts.
