Description
|
Single event groups
|
For simple systems, you can define a thread for each event type
|
Event source
|
Group all events from a single source and handle them with a single task
|
Related information
|
Processing data related to a common purpose
|
Independent processing needs
|
When actions can be clustered into action sequences in which the order within the sequences is
important but the order between sequences is not, these suggest tasks
|
Interface devices
|
A kind of event source, but very common in real-time and embedded systems, you can group events together
from an external interface device (e.g. bus interface or user interface)
|
Event properties
|
Group together events with a common period or aperiodic characteristics. This is demonstrable optimal in
terms of task scheduleability in a priority-based multitasking system.
|
Target objects processing
|
The opposite of "event source", this groups together events related to a target object
|
Safety processing
|
In safety-critical systems, it is common to add additional tasks such as Built In Test (BIT) and watchdog
tasks
