Simulink Blocks in DSP System Toolbox that Support SIMD Code Generation

When certain conditions are met, you can generate SIMD code using Intel AVX2 technology from certain Simulink^® blocks in DSP System Toolbox™. For information on how to generate SIMD code from Simulink blocks, see Generate High Performance SIMD Code on Intel from Simulink Blocks in DSP System Toolbox.

The following table contains a list of Simulink blocks in DSP System Toolbox that support SIMD code generation. The table also details the conditions under which the support is available.
