![]() To achieve the most complete and accurate description, we begin with a deeper look at the defining features of these technologies. What is a Real-Time Embedded System?Ī real-time embedded system combines the technologies of embedded systems and real-time computing. ![]() We'll also offer some real-time embedded systems examples. In this introduction to real-time embedded systems, we'll give a high-level overview of what these unique embedded systems are, how they're designed and classified, and why their functionality is so critical in real world applications. This capability is made possible by the technology of real-time computing. ![]() This means that the embedded microcontroller which controls the airbags must detect that a collision is happening and electronically trigger the release of vehicle airbags - all in just a fraction of a second. When the vehicle stops abruptly in the case of a collision, the airbag must be deployed in a split second to be effective for passengers. Devices that use real-time computing are deployed in applications where their correct functioning can make the difference between life and death.Īs an example, consider the airbag in a conventional family sedan. Real-time computing describes the ability to react to inputs and deliver the prescribed output within a constrained time frame. One of the earliest decision points in embedded systems design is whether the system will require real-time computing capabilities. ![]()
