hi everyone!

    I have a problem when i have a simulation about the fft of 256 point . the transform size i input is 256.but the outcome of the simulation is that the xn_index and xk_index  are changing  from 0 to 377 but not 0 to 255. i don't what is the reason,can someone help me?

OCT 377 = DEC 255 = HEX FF
