An Area-Efficient Large Integer NTT-Multiplier Using Discrete Twiddle Factor Approach

IEEE Transactions on Circuits and Systems - II - Express Briefs, 2023
Number theoretic transform (NTT) method shows great advantages in speed and efficiency for applications such as homomorphic encryption. However, the twiddle factor data consumes a lot of memories. In this brief, we propose a novel data compression method,

Semiconductor Device Simulation at NTT

IEEE Transactions on Computer-Aided Design of Integrated Circuits and Systems, 1985
The current status of semiconductor device simulation at NTT is described. Device simulators at NTT are classified into two categories. One is the conventional macroscopic approach and the other is microscopic particle analysis using a Monte Carlo method. In this paper, these simulators are introduced together with the more interesting results. Through
