DSP Algorithm Acceleration
You can improve simulation throughput for MATLAB® functions using the
dspunfold function to generate a multi-threaded MEX file.
In Simulink®, Dataflow domains automatically partition your model and simulate the system using multiple threads. By adding algorithmic latency to your system, you can further increase concurrency and improve simulation throughput of your model.

- Workflow for Generating a Multithreaded MEX File using dspunfold
This section discusses the recommended workflow of generating the multithreaded MEX and verifying the results using the analyzer.
- Multithreaded MEX File Generation
This example shows how to use the
dspunfoldfunction to generate a multithreaded MEX file from a MATLAB® function using unfolding technology.

- How Is dspunfold Different from parfor?
This page should detail the users on when to use dspunfold and when to use parfor.
- Dataflow Domain

- Multicore Simulation and Code Generation of Dataflow Domains
Types of parallelism. Simulation and code generation of dataflow domains using multiple threads.
- Model Multirate Signal Processing Systems Using Dataflow
Use a Dataflow Subsystem to automatically calculate frame sizes in multirate systems.
- Perform Multicore Analysis for Dataflow
When a subsystem in a model is configured to use a dataflow execution domain, the Multicore tab is activated on the Simulink toolstrip.
Why Does the Analyzer Choose the Wrong State Length?
This section discusses the example where the state length depends on the input which causes verification failure. Debugging steps are also included.
Why Does the Analyzer Choose a Zero State Length?
This section discusses the example where the input does not have an immediate effect on the output. Hence, state length of 0 is considered in spite of the algorithm containing states.
