I have a sin signal that is measured with accelerometer, after converting to digital value, it will transfer to FFT IP core for detecting the frequency. this frequency should enter to another block to generate sin and cos signal with unit amplitude. I think the DDS Ip core can receive the phase and generate the sinusoidal signal. is it right? but I have a frequency, how I can convert to phase?
Please let me know how can I configure FFT and DDS? is there any special configuration that I should attention on it.
in my opinion, I can't use the cordic, because the input signal
