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 ...

The best part about real-time OS (RTOS) availability in 2024 is that we developers are positively spoiled for choice, but as a corollary this also makes it a complete pain to determine what the ...

Senior Editor The simplest embedded systems center on microcontrollers running a single control loop. The loop may poll inputs or be interrupt driven, but as long as no other task ever requires ...

Real-time scheduling algorithms determine the order and timing with which tasks execute in embedded systems subject to stringent timing constraints. These algorithms seek to guarantee that critical ...

Most of the computers we interact with on a day-to-day basis use an operating system designed for flexibility. While these are great tools for getting work done or scrolling your favorite sites, they ...

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) ...

The actual definition of real-time database versus the abused interpretation used by marketers of real fast database systems. The interplay of transient and persistent memory, and hard and soft ...
