Schedulability
- Schedulability
- the performance
quality subfactor
that models the extent to which events and behaviors are deterministic
and can be accurately scheduled
Schedulability is typically measured in terms of:
- Percentage of behaviors that are deterministic for a given set of inputs when in a given state
- Accuracy of time when scheduled events and behaviors occur
See
schedulability requirements.
Typical mechanisms for improving schedulability include:
- Real-time OS
- Cyclic executive
- No automatic garbage collection
The following guidelines have been found to be useful with
regard to producing schedulability:
- Schedualability may have significant impacts on safety, security, and obtaining associated certifications.
