The Importance of Real Time Embedded Systems
The pace of the technology is rapidly changing every year, new technologies are evolving faster than ever. The cost and risk of delivering higher quality in production are increasing day by day. The emergence of embedded systems had reduced the not only cost and risk but also improved the quality.
Embedded systems can be referred as the computer system that is embedded in electrical or mechanical systems. The real-time embedded systems are useful for monitor & controlling external environments.
The external environment is linked to the computer system by using input/output interfaces, actuators, and sensors. The external environment may consist of biological and physical objects like animals as well as humans. While to understand the behavior of the external world the computer systems are set to follow certain parameters. This is called understanding the real-time behavior of the environment through an embedded system.
The usage of the real-time embedded system has practically improved in the recent years. It has widely from bigger industries like military, aeronautics, robotics to commercial industries like telecom automobile and kitchen appliances.
It is a known fact that the embedded systems are allied with software technology. Because of the software technology determines the success and performance of the embedded systems.
But the embedded systems are not exactly a software application, it’s has a set of inherent characteristics that distinguish from mainstream software applications. The real-time embedded systems are meant to respond to real world situations, which strictly following the parameters set by the environment with which they interact. The utmost importance of the main characteristic of the embedded systems is it must answer to a set of external inducements within inflexible and precarious time constraints.
A real-time application will normally consist of both hard and soft components. A nuclear reactor is a much say example for the hard real-time system. It does not only detect the failure but also quickly enough in the situations to prevent the meltdown. Soft components are little less stern in time & accuracy. In one or other form, every car that comes out of any production centers uses embedded technology.
Embedded systems include Real Time Operating systems, the real time operating system hides all the backend functionality, it just presents a screen to the user and its hide hides all the computation.
The real-time operating system (RTOS) helps the user to use maximum time and resources to get the desired output. The real-time operating system takes cares of execution & monitoring & controlling processes. RTOS has widely used in the sectors like aircraft, cars, robots & machines manufacturing units. RTOS give more outputs by keeping all the devices and resources active. The RTOS is used in video games, digital appliances, and robotic industry.
