Proxy Task

A placeholder for a task in your application

Since R2019b

Libraries:
SoC Blockset / Processor Task Execution

Description

The Proxy Task block simulates the effect of a timer-driven task in your SoC application without an explicit implementation. This block can be used as a placeholder for timer-driven tasks to be developed in the future, or implemented simultaneously by another developer.

When added to your processor reference Model block, it causes the processor model, when set to schedule rates by ports, to display a periodic event port with a sample time equal to Sample Time parameter. Connect the periodic event port to a timer-driven task output port on the Task Manager block.

Examples

Task Execution

Simulate task execution and how to generate code and run it on an SoC hardware board.

Open Example

Ports

Input

Port_1 — Function-call from Task Manager block

scalar

A function-call signal that triggers the Proxy Task block when operating as an event-driven task.

Dependencies

To enable this port, set the Type property to Event-driven.

Data Types: function-call

Parameters

Type — Type of task

Timer-driven (default) | Event-driven

Select the type of task as either Timer-driven or Event-driven.

Sample Time — Sample time

1 (default) | positive scalar

Sample time of the block.

Note

• The Sample Time of the Proxy Task block must match the sample time of the corresponding timer-driven task from the Task Manager block.

• The Sample Time of the Proxy Task block should be unique within the model. When other blocks in the model use the same sample time, the duration of the task defined by Proxy Task block cannot be guaranteed in code generation.

Dependencies

To enable this parameter, set the Type property to Timer-driven.
