Now I use dsplib in my davinci DM6446 project. I have some questions.
1.16x16 fft How can I get the correct output? The output is short t precision or r Q.15 format. How can I understand it?
2.I input a 256*256 's picture (GRAY every pix has a 8-bits) . I input the 256*256 picture in the real components and the imaginary components are all 0. And I watch the output .The output : the real components and the imaginary components all have 16-bits . How can I get the correct results? How can I transform it correctly?
Thanks !
