+The generated files need to include the `sdf/src/GenericNodes.h` and the nodes used in the graph and which can be found in `sdf/nodes/cpp`.
 
 If you have declared new nodes in `graph.py` then you'll need to provide an implementation.

   - Binary function with header `void function(T* srcA, T* srcB, T* dst, int nbSamples)`
 - CMSIS-DSP function:
   - It will detect if it is an unary or binary function.

+  - The name must not contain the prefix `arm` nor the the type suffix
   - For instance, use `Dsp("mult",CType(F32),NBSAMPLES)` to use `arm_mult_f32`
   - Other CMSIS-DSP function (with an instance variable) are requiring the creation of a Node if it is not already provided
 - CFFT / ICFFT : Use of CMSIS-DSP CFFT. Currently only F32 and Q15
