i m using 512 point FFT IP core in V6 FPGA to calculate the frequency of the input signal, i m getting the correct peak and amplitude for the same . the peak's real and imaginary value i have to give to the cordic ip core(atan) to get the phase of the input signal . the input to the fft is a 10 bit samples from adc in 2's complement format the output of the fft is "unscaled" so it is 2's complement 20 bit ,what i m not gettting is how to fed the data to the input of the cordic .the normalization is required or not ??? if anybody can help on this???
