| Concept | Brief Explanation | |---------|--------------------| | | Missing a deadline causes system failure (e.g., airbag control) | | Soft RTOS | Missing a deadline reduces performance but not catastrophic (e.g., video streaming) | | Jitter | Variation in task completion time | | Priority Ceiling Protocol | Solves priority inversion | | Periodic vs. Aperiodic tasks | Fixed interval vs. event-driven tasks | | Rate Monotonic Scheduling (RMS) | Static priority assigned based on period | | Earliest Deadline First (EDF) | Dynamic priority based on closest deadline |
Missed deadlines make the data useless, but do not cause physical damage (e.g., algorithmic financial trading). Architectural Deep Dive: The Role of RTOS Embedded And Real Time Systems By Kvkk Prasad Pdf
