Task Trigger

Trigger task execution in your application

Since R2023b

Libraries:
SoC Blockset / Processor Task Execution

Description

The Task Trigger block triggers execution of an event-driven task in your application. Connect the output of this block to the event port of the respective task in the Task Manager block. Place this block in the appropriate task in the reference model.

You can place more than one of these blocks in the same task.

Use this block to enable efficient task schedules with explicit synchronization between tasks.

Ports

Output

expand all

Port_1 — Output trigger
scalar

This port sends a task signal that triggers the Task Manager block to execute the associated task.

Data Types: rteEvent

Extended Capabilities

C/C++ Code Generation
Generate C and C++ code using Simulink® Coder™.

To automatically generate C code for your design, and execute the code on an SoC device, use the SoC Builder tool. For more information on generating code for SoC designs, see Use SoC Builder to Generate SoC Design.
To generate and execute C code for your SoC models, this block requires Embedded Coder^® and one of these support packages:
- SoC Blockset™ Support Package for AMD FPGA and SoC Devices
- SoC Blockset Support Package for Intel^® Devices
- SoC Blockset Support Package for Embedded Linux^® Devices
To use this block, you must set Hardware Board in the configuration parameters to a supported board. You can then follow the instructions to configure the board. For more information, see Create an Embedded Linux Device Configuration.

When deployed to a supported hardware board, this block uses the POSIX semaphore API to implement a task trigger.
