System objects in DSP System Toolbox that Support SIMD Code Generation

R2026b

When certain conditions are met, you can generate SIMD code from MATLAB^® System objects in DSP System Toolbox™ using these two approaches:

• Intel^® AVX2 code replacement library — Requires MATLAB Coder™ license and Embedded Coder^® license. For more information on this workflow, see Use Intel AVX2 Code Replacement Library to Generate SIMD Code from MATLAB Algorithms.

• InstructionSetExtensions configuration parameter — Requires MATLAB Coder license or Embedded Coder license. For more information on this workflow, see Generate SIMD Code for MATLAB System Objects for Intel Platforms, Generate SIMD Code from MATLAB System Objects for Apple silicon and ARM Cortex-A Processors.

The following table contains a list of all System objects in DSP System Toolbox that support SIMD code generation. For more information on the conditions under which these objects generate SIMD code, see the Extended Capabilities > C/C++ Code Generation sections in the respective object reference pages.
