v1.2.1 contains following fixes:

  • [dsp] Call appropriate NEON butterfly functions in NE10_fft_int32.neon.c
  • [dsp] Prevent overflow by moving scaling in front of butterfly
  • [dsp] Link stdc++ for static build
  • [all] Switch to intrinsic on iOS
  • [dsp] Fix NE10_INLINE_ASM_OPT for RFFT
  • [math] Limit the range of input to avoid the failed tests in math module
  • [dsp] Fix test_suite_fft_int32.c fails under armv7
    • For 4-point and 8-point FFTs, we fall back to VFP because they are too short for NEON optimizations
  • [all] Main fuction in tests return 0 if all tests pass
  • [all] Enable neon code on ARM32 in physics, dsp and image modules

It also contains a small improvement:

  • [dsp] Improve data layout in RFFT float32
