Event-Based Scheduling

Asynchronous event handling, rate transitions, timers, event data

Models can include blocks for generating code that handles asynchronous events, such as:

For simulation, you can import asynchronous event data into a function-call subsystem.

Blocks

Asynchronous Task Specification	Specify priority of asynchronous task represented by referenced model triggered by asynchronous interrupt
Async Interrupt	Generate Versa Module Eurocard (VME) interrupt service routines (ISRs) that execute downstream subsystems or Task Sync blocks
Idle Task	Create free-running task
Task Sync	Run code of downstream function-call subsystem or Stateflow chart by spawning an example RTOS (VxWorks) task

Asynchronous Events
Design models that support execution of blocks in response to events that occur asynchronously to the periodic timing source of the system.
Rate Transitions and Asynchronous Blocks
Use Rate Transition blocks to handle data transfers to and from asynchronous blocks.
Generate Interrupt Service Routines
Generate an interrupt service routine (ISR) that is associated with a specific VME interrupt level.
Pass Asynchronous Events in RTOS as Input to a Referenced Model
Generate code for a model that triggers asynchronous events that get passed as input to a referenced model.
Timers in Asynchronous Tasks
Maintain absolute and elapsed timing data for blocks that execute in the context of an asynchronous task with the code generator.
Create a Customized Asynchronous Library
Create custom blocks that support handling of asynchronous events with vxlib1 library blocks as templates.
Import Asynchronous Event Data for Simulation
Import asynchronous event data into a function-call subsystem.
Generate Component Source Code for Export to External Code Base
Integrate C/C++ source code, which you generate from a model component, with code developed outside the Simulink^® environment.
Simulink Function Blocks and Code Generation
Generate reusable code from Simulink Function blocks.
