Help needed in VHDl code for calculating the I and Q phase component for a ADC signal

Hello all, I am designing a DDC in which I need to calculate the In phase(I) and the Quadrature phase(Q) components of my ADC signal. I know how these components are manually calculated from som...

you have already done that at mixer output.

However I am not clear about other things. how you process at such high sample rate after ADC
