Abstract
Generally discussed herein are devices, systems, and methods for performing a number theoretic transform (NTT)/inverse NTT (INTT). A circuit for NTT/INTT can include a first butterfly operator circuit (BOC) that generates first and second output coefficients based on first and second polynomial coefficients and a twiddle factor, a second BOC that operates in parallel with the first BOC and generates third and fourth output coefficients based on third and fourth polynomial coefficients and the twiddle factor, a third BOC that operates in series with the first and second BOCs and generates fifth and sixth output coefficients based on the first and third output coefficients and a second twiddle factor, and a fourth BOC that operates in series with the first and second BOCs and in parallel with the third BOC and generates seventh and eighth output coefficients based on the second and fourth output coefficients and a third twiddle factor.
