Watchdog Timer for Fault Tolerance in Embedded Systems.

Embedded artificial intelligence encompasses a diverse range of technologies, from advanced algorithms to highly specialized computing systems. Intelligent embedded systems are playing an increasingly crucial role in various industries such as automotive, aerospace, healthcare, and IoT. When considering the place that intelligent embedded systems take in our daily lives, it is very important to understand how critical their security is. In order to ensure their high performance, energy efficiency, and robustness, it is imperative to ensure rigorous task scheduling. We are interested in the problem of hard real-time fault-tolerant scheduling for periodic and independent preemptive tasks. This paper focuses on proposing a fault-tolerant scheduling algorithm for these systems. By using the Watchdog Timer, which allows intelligent embedded systems to be more autonomous by detecting processor errors and adopting the Earliest Deadline First (EDF) algorithm to allow our system to respect time constraints. The objective is to improve reliability and efficiency by ensuring the execution of critical tasks despite the presence of faults. Designing and implementing a fault-tolerant scheduling algorithm for embedded systems is a crucial aspect in various industries. This helps to improve the reliability and security of intelligent embedded systems, which is essential to ensure the smooth operation of the system. [ABSTRACT FROM AUTHOR]
