- Remaining arithmetic budget
- 16 ms
Arithmetic budget only. Interrupts, jitter, communications and worst-case execution must be measured; this is not a safety or schedulability guarantee.
Formula & guidance
utilization % = execution ÷ interval × 100
Arithmetic budget only. Interrupts, jitter, communications and worst-case execution must be measured; this is not a safety or schedulability guarantee.
