Problem with the function DSP_IFFT16x16



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
