In this paper, we present a multiplier based on a sequence of approximated accumulations. According to a given splitting point of the carry chains, the technique herein introduced allows varying the quality of the accumulations and, consequently, the overall product. Our approximate multiplier trades-off accuracy for a reduced latency—with respect to an accurate sequential multiplier—and exploits the inherent area savings of sequential over combinatorial approaches. We implemented multiple…
