Simulink Blocks in DSP System Toolbox that Support SIMD Code Generation

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

• The code replacement library DSP Intel AVX2-FMA or ARM Cortex-A –– Requires Embedded Coder^® license. For more information on this workflow, see Use Intel AVX2 Code Replacement Library to Generate SIMD Code from Simulink Blocks and Optimize Code for ARM Cortex-A Processors (Embedded Coder).

• The Leverage target hardware instruction set extensions model configuration parameter –– Requires the Simulink Coder™ license or the Embedded Coder license. For more information on this workflow, see Use Target Hardware Instruction Set Extensions to Generate SIMD Code from Simulink Blocks for Intel Platforms and Use Target Hardware Instruction Set Extensions to Generate SIMD Code from Simulink Blocks for ARM Cortex-A Processors.

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