Hi, I'm trying to use a Cortex-M4 for multiple tasks in real-time digital signal processing. Based on a fixedpoint Simulink model the C-Code for the target shall be produced with the Embedded Coder. I know that (under the right conditions) the CMSIS code replacement library (CRL) can be used to translate DSP Blocks into efficient code for classic operations like FIR and so on ( ). But for the sake of performance I want the Embedded Coder to replace the standard math operations like multiplication an division with their SIMD equivalents( ). Is this feature even implemented in the Embedded Coder (Hardware Support Package for ARM Cortex is installed) and if so, what are the prerequisites for a successful replacement? Best regards Philipp
