Jitter
- Jitter
- the performance
quality subfactor
representing the degree to which the variability of the time intervals between controlled periodic actions
remains within its designated constraints
Jitter is typically measured in terms of:
- The maximum/minimum time intervals between specific periodic events or behaviors when in a given state.
- The standard deviation in the time distribution of specific periodic events or behaviors when in a given state.
See
jitter requirements.
Typical mechanisms for improving jitter include:
- Real-time OS
- Cyclic executive
- No automatic garbage collection
The following guidelines have been found to be useful with
regard to jitter:
- Jitter may have significant impacts on safety, security, and obtaining associated certifications.
