HI!
I am working with the DSP library dsp_lib_c66x_3_0_0_7 provided with CCSv.5.0.23 on the platform of 6678.
Does the output of IFFT function DSP_IFFT16*16 output require any upscaling.
I need to filter a raw image data (.raw) .
The data is read as short datatype and its FFT (32 point ) is multiplied with a filter kernel. Its 32 point IFFT requires a downscaling by a factor of 2.
I used the following functions
gen_twiddle_fft16x16
gen_twiddle_ifft16x16
DSP_fft16x16
DSP_ifft16x16
thanks
Sohal
