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 ...

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 ...

Modern embedded systems are expected to operate with predictable timing, continuous reliability, and near-instantaneous response under increasingly complex workloads. From automotive control units and ...

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 ...

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 ...

A real time system must respect time constraints to ensure that its execution makes functional sense. A real-time operating system or RTOS (sometimes known as a real-time executive kernel) is a ...
