Abstract

This paper describes a VLSI network for the multiplication of two N-bit integers, for very large N. The network, with its area 0(N) and operation time 0(vN), matches, within a constant factor, the known theoretical O(N2) lower bound to the area × (time)2measure of complexity in the VLSI model of computation. The network, which is based on the discrete Fourier transform, has a
