Question:An embedded real-time operating system uses a certain scheduling algorithm. When a task is nearing its deadline, the scheduling algorithm adjusts the priority of that task to the highest in the system, allowing it to acquire CPU resources for execution. What type of scheduling algorithm is this?. A: Priority Scheduling Algorithm B: Preemptive Priority Scheduling … Read more

Let’s illustrate this issue with a concrete example. How does a typical task system handle information in embedded systems? The process looks like this: • Retrieve new data • Filter/Process data • Output data Pretty straightforward, right? We know that for real-time embedded system design, the main goal is determinism and minimizing jitter. The three … Read more
