Task Trigger Merge

Merge multiple task triggers into one trigger

Since R2023b

Libraries:
SoC Blockset / Processor Task Execution

Description

The Task Trigger Merge block creates a single task trigger from a set of task triggers. Connect Task Trigger block outputs to the input ports of this block, and connect the output of this block to the event port of the respective event-driven task in the Task Manager block.

Place this block in the top model.

Ports

Input

expand all

Port_1 — Input trigger
scalar

This port receives multiple task triggers and merges them into one.

You define the number of Port_N input ports by specifying the Number of input task triggers parameter.

Data Types: rteEvent

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

Parameters

expand all

Number of input task triggers — Number of triggers to merge
2 (default) | positive integer

Number of task triggers to merge into one output trigger, specified as a positive integer.

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.
