Well, there is CMSIS DSP / math, i.e. ARM's low level lib as part of the 
whole CMSIS, a low level lib / register definitions etc, which is a 
layer below stuff like the ST "cube" library.
It has code optimized for the different ARM cores like cortex M4, for 
common DSP functions like performing filter operations.
Haven't really tried them or compared to anything else, as I have only 
made some baby steps in DSP land so far.
Maybe someone else can comment of how useful that really is.
