Supported DSP System Toolbox System Objects with Ne10 Library for 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 DSP System Toolbox™ System object™ that can be used with the Embedded Coder® Support Package for ARM® Cortex®-A Processors 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. The Ne10 library supports these DSP System objects only when you set specific properties, as indicated in the following table:
