Calculation method
Calculation method
Processor utilization
Sum execution/period on one ideal preemptive processor.
Model utilization bound
EDF bound1 for deadline=period; rate-monotonic n(2^(1/n)−1).
Screening result
EDF exact utilization condition under ideal independent implicit-deadline assumptions; RM sufficient test only.
Symbols and units

- Periodic tasks [execution time,period,relative deadline]
- b
- Model: 0 EDF implicit deadline; 1 rate-monotonic sufficient bound
Use the units shown. A list keeps the order in which you enter its values. The symbol ^ means “raised to the power of”.
Assumptions & limits
Assumptions & limits
- Independent periodic tasks with deadlines equal to periods, one ideal fully preemptive processor, no blocking or scheduling overhead. Constrained/arbitrary deadlines are explicitly rejected rather than applying an invalid utilization rule. Quantities are deterministic calculations from supplied observations and assumptions; no external data is fetched. Supported limits: Finite inputs only; numeric fields bounded as labelled. Lists and JSON records are limited to 256 entries unless a stricter tool bound is stated. No automatic design approval, legal conclusion, treatment recommendation or safety certification. Model: 0 EDF implicit deadline; 1 rate-monotonic sufficient bound: minimum 0, maximum 1.
