After introducing interrupts and the foreground/background architecture, I am finally ready to tackle the concept of a Real-Time Operating System (RTOS). In this first lesson on RTOS (commonly ...

This fifth lesson on RTOS finally addresses the real-time aspect of the “Real-Time Operating System” name. Specifically, in the video lesson 26, you add a preemptive, priority-based scheduler to the ...

A real-time system must respect time constraints to ensure that its execution makes functional sense. It must be deterministic, ensuring the execution of system processes a priori. After analyzing the ...

Real-time systems and embedded computing have become foundational to modern engineering, underpinning applications from industrial automation and automotive control to aerospace and telecommunications ...

A newly released update to Linux delivers kernel pre-emption, improved scheduling, and a Posix (Portable Operating System Interface for Unix) for enhanced real-time performance. Depending on the ...

Opinions expressed by Digital Journal contributors are their own. The telecommunications industry is one of the most dramatically transformed industries in contemporary history, principally due to ...

While the GNU/Linux Operating System is gaining popularity in research and student communities as well as in the business world, its impact is still limited for all those application areas requiring ...

Embedded systems are increasingly prevalent in nearly every aspect of human life. Innovations made possible by embedded systems are making our lives healthier, safer, cleaner, and more stimulating.

Why external consistency is so important for a hard real-time database. Maintaining a transaction timeline. The impact of a transaction-scheduling policy. A real-time database-management system (DMBS) ...

Any electronic system that uses a computer chip but is not a general-purpose desktop or laptop computer, tablet or smartphone. Embedded systems use microcontrollers (MCUs), microprocessors (MPUs) or ...
