Christophe Favergeon 8092cc61f9 CMSIS-DSP: New MFCC Q15 and Q31
arm_cmplx_mag_q15 reworked to be more accurate but less efficient.

New function arm_cmplx_mag_fast_q15 introduced to retain previous
(less accurate) but faster behavior.

Improvement to Python wrapper to support the new functions.

Christophe Favergeon 99dc566e87 CMSIS-DSP: MVE versions of vlog q15 and q31 and PythonWrapper fix
PythonWrapper was no more building on windows due to a too long
link command line.

A temporary fix was made. But on long term the wrapper must be refactored
into submodules to allow to more easily add new functions.

Christophe Favergeon 3d264cfabb CMSIS-DSP: MFCC F32
MFCC F32 implementation
MFCC F32 tests
MFCC F32 in Python wrapper
Python wrapper structure updated to support submodule like
cmsisdsp.mfcc and cmsisdsp.fixedpoint
PythonWrapper tests updated to use the new fixedpoint
cmsisdsp.mfcc is used to generate the mel filter, dct and window coefficients.

Christophe Favergeon ab33fa64d7 CMSIS-DSP: Synchronous Data Flow
Set of Python scripts used to describe synchronous data flow networks
and generate a static scheduling.

It is working with CMSIS-DSP and a few standard nodes provided as C++ or Python classes.
It can be easily extended.

It is also working with the Python wrapper for CMSIS-DSP.

Detailed documentation in the SDFTools/README.md

Christophe Favergeon 9a254bc926 CMSIS-DSP: Improvements for building with gcc on M55.
Solve most of f16 issues. But there are still some remaining
build issues with gcc10q4.

2 functions are reverting to scalar version when build with gcc on M55.
(Since Helium versions of those functions are not building).

Christophe Favergeon 3bf2e2eda6 CMSIS-DSP: Enable build with MSVC compiler.
The goal of this commit is to allow the build of CMSIS-DSP on Windows to
enable the use of the library from Python or Matlab.

The Python wrapper has also been simplified and is now using the
CMSIS-DSP directly without requiring specific include files or source files.
