Supported Deep Learning Toolbox Functions with CMSIS Library for ARM Cortex-M Processors

R2026b

Deep learning layer functions that can be used with the Embedded Coder^® Support Package for ARM^® Cortex^®-M Processors require specific conditions to allow code replacement with the common microcontroller software interface standard (CMSIS) library.

You use this code replacement when generating C code from a model. The CMSIS library support these Deep Learning Toolbox™ layer functions only when you set specific properties, as indicated in the following table.
