Keyon Jie d2cfa10f50 cmocka: add cmocka unit test for fft library ... Add cmocka unit test for FFT library, including fft with size 1024/256, fft + ifft with SNR test, fft for 2 channels. Implement helpers to accept samples put in comp_buffer for both real and complex FFT, the helper fft_real_2() is implemented to speed up the FFT for dual channels inputs up to two times. All theses helpers should be used for unit test only. Suggested-by: Amery Song <chao.song@intel.com> Signed-off-by: Keyon Jie <yang.jie@linux.intel.com>		2021-04-15 17:30:48 +08:00
