CMSIS-DSP

• Internal rework of lots of files to be able to build Neon versions when targetting Cortex-A
  • Cortex-A build is not part of the pack release and should not impact Cortex-M build
  • Other changes in the github repository : Cortex-A build with Neon using cmake and Zephyr module
  • Correction of arm_biquad_cascade_df1_f32 (#290) : out of buffer access with Helium
  • Fix overfl...

• Improvements to documentation
• Added arm_fir_decimate_f64
• Removed some gcc workarounds that are no more needed for Helium
• Removed redundant test in arm_atan2_q15 and arm_atan2_q31
• Replaced INFINITY by maximum positive float
• Replaced hex constants with 2's complement equivalents
• Added C++ template extension (outside of pack - headers available from github repository)
• A...

• Switched to semantic versioning
• Corrections to MFCC
• Updated support for cmsis build tools 2.0
• Compute graph removed. It is now part of CMSIS-Stream
• Github issues:
  • 95,96,105,106,108,111,112
• New FFT initializations to allow linker to do code size optimizations
  • If you know the size of the transform at build time, prefer functions like arm_cfft_init_64_q15 to function...

What's Changed

• Missing header added to arm_math.h
• Documentation improvements
• Improvements to the generic nodes of the compute graph
