What are real-time systems and why are they important?
Real-time systems are systems that have to meet certain timing constraints in order to function correctly and reliably. They have to react to events or inputs from the environment or other systems within a predefined deadline, otherwise they may cause serious consequences such as system failure, data loss, or even harm to human lives.
Definition and characteristics of real-time systems
A real-time system can be defined as a system that has to satisfy both functional and temporal requirements . Functional requirements specify what the system has to do, while temporal requirements specify when the system has to do it. For example, a functional requirement of an airbag system is to deploy the airbag when a collision is detected, while a temporal requirement is to deploy the airbag within 10 milliseconds after the collision.
Some characteristics of real-time systems are :
They have to deal with concurrency, which means they have to handle multiple tasks or processes that run simultaneously and share resources.
They have to deal with unpredictability, which means they have to cope with uncertainties and variations in the execution time, arrival time, or priority of tasks or events.
They have to deal with resource constraints, which means they have to optimize the use of limited resources such as memory, CPU, bandwidth, or power.
They have to deal with dependability, which means they have to ensure the correctness, reliability, availability, safety, and security of the system.
Examples and applications of real-time systems
Real-time systems are ubiquitous in our daily lives and society. Some examples and applications of real-time systems are :
Aerospace systems such as flight control systems, navigation systems, or satellite systems.
Automotive systems such as anti-lock braking systems, adaptive cruise control systems, or engine control systems.
Robotics systems such as industrial robots, autonomous robots, or humanoid robots.
Industrial control systems such as chemical plants, power plants, or manufacturing plants.
Multimedia systems such as audio/video streaming, video games, or virtual reality.
Healthcare systems such as pacemakers, ventilators, or surgical robots.
Challenges and requirements of real-time systems
Real-time systems face many challenges and requirements in their design, development, and operation. Some of them are :
Scheduling, which is the problem of deciding when and how to execute the tasks or processes of the system to meet the temporal requirements.
Resource access control, which is the problem of managing the access and allocation of shared resources among concurrent tasks or processes.
Validation, which is the problem of verifying and testing that the system meets the functional and temporal requirements.
Adaptation, which is the problem of adjusting the system behavior or parameters to cope with changes in the environment or system conditions.
Quality of service, which is the problem of providing a certain level of performance, reliability, or satisfaction to the users or customers of the system.
