We will have more to say about both Tracealyzer 4 and ArmTechCon in the coming weeks, but there's one little [...]
Priority inversion at work – the high-priority (red) task is blocked by lower priority tasks. The central idea underlying an RTOS with a fixed-priority scheduler is that a high-priority task should be scheduled ahead of one with lower priority. If necessary, the RTOS can even pre-empt the running task, forcing it to yield the CPU to [...]
Our Korean distributor Dioiz is running a hands-on seminar on embedded development with, among other tools, Tracealyzer this week. It is sold out by now, but there will be a second event on November 22 and Dioiz has let us know that applications are welcome. More info here – note though that both the invitation and the [...]
When you have a task in your system that is supposed to execute at regular intervals, say for instance that it needs to read a sensor value every 5 milliseconds, then you have a system that is sensitive to random delays – also known as “jitter”. When your task experiences jitter, it sometimes has to [...]
