The DSP System Toolbox™ Support Package for ARM® Cortex®-M Processors, when paired with Embedded
Coder®, enables you to generate optimized C code from MATLAB® System objects™ or Simulink® blocks.
This is done for ARM Cortex-M processor-based systems using the Cortex Microcontroller Software
Interface Standard (CMSIS) library. Benefits include an immediate increase in performance when
compared to standard C code generation.
The generated code optimization is provided via Code Replacement Library (CRL) for CMSIS functions,
including math operations such as abs, add, sub and mult, and DSP algorithms such as FIR, FFT and IFFT .
The CRL for CMSIS is supported in both Simulink-to-C and MATLAB-to-C workflows on all MathWorks
supported hardware platforms. As an example of MATLAB-to-C workflow, the white paper illustrates how to port the generated C code from MATLAB (R2014b) to IAR Embedded Workbench®.
