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.
This first version is not very accurate due to problems with the log.
A coming commit will improve the log accuracy.
Issues #1305 and #1304 also corrected as part of this commit.
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.
(For our internal use. In short term, we won't give support about it).
CMSIS-DSP: Update to cmake build for the testing framework
CMSIS-NN:Implementation of arm_fully_connected_s8
Use API and quantization compatible with TF Lite.
DSP_Lib_TestSuite can be built with cmake and run on FVP.
Some issues with CMSIS-DSP cmake where discovered and corrected.
Comments added to arm_biqaud_cascade_df2T+f32 since the Neon version
must be initialized differently (and thus the corresponding test
in DSP_Lib_TestSuite will have to be updated to pass with Neon version).
Compilation symbols have been introduced to allow to include only the
FFT tables which are useful in a given application.
The README.md in DSP is giving more details.
