Ne10 Conditions for MATLAB Functions to Support ARM Cortex-A Processors

Note

The GCC ARM Cortex-A code replacement library is no longer visible in the code replacement library selector. To use the optimizations that were in this code replacement library, set the parameter Code replacement libraries to ARM Cortex-A CMSIS.

Each MATLAB^® function that you can use with the Support Package for ARM^® Cortex^®-A processors with Neon extension requires specific conditions to allow code replacement with the Ne10 Library. You use this code replacement when generating C code from a model or from MATLAB code.

If you do not meet the specific requirements, then the C code is generated to run on the ARM Cortex-A processors. However, this generated code does not use Ne10 library support.

The Ne10 library supports these MATLAB functions only when you set specific properties, as indicated in this table:
