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 ...

With the advent of multithreaded/multicore CPUs, even embedded real-time applications are starting to run on SMP systems—for example, both the Xbox 360 and PS/3 are multithreaded, and there even have ...

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 ...

Examine a computer-controlled machine built in the last 20 years and you’ll note a common design practice. The machine’s real-time control functions, its vision system (if there is one), and its human ...

The proliferation of multicore processors has done more than provide a boost in processing power to server applications. Multicore chips also pose the opportunity to revolutionize how embedded systems ...

As more complex devices with higher levels of integration are inserted into real-time systems, traditional testing methods are becoming obsolete. The most difficult obstacle to thorough testing of ...

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 ...
