What I was taught is that hard real time has a bounded response time: we are always able to respond to an event in less than some specified time T. It doesn't mean fast, just that there is a hard ...

Real-time is an often misunderstood and misapplied property of operating systems. One definition of the term can be found in the FAQ for the comp.real-time newsgroup: “A real-time system is one in ...

An RTOS is a specialized operating system designed to handle time-critical tasks with precision and reliability. Unlike general-purpose operating systems like Windows or macOS, an RTOS is built to ...

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 ...

When do you need to use a real-time operating system (RTOS) for an embedded project? What does it bring to the table, and what are the costs? Fortunately there are strict technical definitions, which ...

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 ...

It’s easy to forget that embedded Linux can’t do everything for all embedded developers. While it is suitable for some applications with many megabytes of memory and powerful processors, there are a ...

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 ...
