Time-Based Scheduling

Solver, sample rates and transitions, tasking, real-time execution

Use fixed-step or variable-step solvers for models that run at one or more sample rates. Single-tasking and multitasking execution modes are available only for fixed-step solvers. A real-time program executes model code synchronously with real time.

To generate code that executes in real time, identify and handle sample rate transitions within the model.

Topics

Time-Based Scheduling and Code Generation
Generate code that meets real-time execution requirements after reviewing sample time and tasking mode considerations.
Configure Generated C Function Interface for Model Entry-Point Functions
Learn about generated C entry-point functions, configuration options, and how to interface with them.
Execution of Code Generated from a Model
Execute code generated from single-tasking and multitasking models for rapid-prototyping and embedded system run-time environments.
Modeling for Single-Tasking Execution
Use the base sample rate of a model to define the time interval during which blocks in the model execute.
Modeling for Multitasking Execution
Include blocks that use different sample rates, or use different sample rates for continuous and discrete parts of a model.
Handle Rate Transitions
Handle transitions between blocks with different periodic sample rates.
Configure Time-Based Scheduling
Configure model configuration parameters that are relevant to time-based scheduling of generated code.
Optimize Memory Usage for Time Counters
Optimize memory that the code generator allocates for an elapsed time counter.
Time-Based Scheduling Example Models
Models that show time-based scheduling scenarios.
