Higher priority value indicates higher task priority

Priority ordering for real-time system targets

Model Configuration Pane: Solver

Description

Use this option to indicate whether a higher task priority is indicated by a lower value or a higher value in the real-time target. Code generation uses this information to implement asynchronous data transfers.

Settings

off (default) | on

Default: Off

on

The real-time system assigns higher priority values to higher priority tasks. For example, a task with a priority value of 8 has a higher task priority than a task with a priority value of 4.

Rate Transition blocks treat asynchronous transitions from a rate with a lower priority value to a rate with a higher priority value as a low-to-high rate transitions.

off

The real-time system assigns lower priority values to higher priority tasks. For example, a task with a priority value of 4 has a higher task priority than a task with a priority value of 8.

Rate Transition blocks treat asynchronous transitions from a rate with a lower priority value to a rate with a higher priority value as high-to-low rate transitions.
