Task Trigger block

To add a block to a model, double-click the canvas and start typing the block name. Then, select the block from the list.

Libraries:
SoC Blockset for AMD / SoC System Simulation / Processor Task Execution
HDL Coder / SoC System Simulation / 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 (SoC Blockset) 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

Port_1 — Output trigger

scalar

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

Data Types: rteEvent

Programmatic Use: Add Block

To add the block programmatically, use the add_block function with one of these library block paths as the source.

"proctasklib/Task Trigger"

"proctasklib/Task Trigger"

Example: add_block("proctasklib/Task Trigger","myModel/myBlock",MakeNameUnique="on")

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 (SoC Blockset) tool. For more information on generating code for SoC designs, see Use SoC Builder to Generate SoC Design (SoC Blockset).

• 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

  • HDL Coder™ Support Package for Intel^® FPGA and SoC Devices

  • SoC Blockset Support Package for AMD FPGA and SoC 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.

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