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 ...

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 ...

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 ...

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 ...

Medical device companies, especially those with real-time embedded-system products, are often burdened with lengthy verification cycles. Even small development efforts can result in months of ...
