In this paper, a digit-serial multiplier based on shift-accumulation (DSAAM)  is compared to a digit-serial/parallel multiplier (S|/Ppipe) . Both the studied multipliers can be pipelined to an arbitrary degree and are, therefore, well suited for high-throughput implementation. In our study bit-level pipelining was considered. Neither of the multipliers have been implemented in a deep-submicron technology previously, which motivates our study. The multipliers were implemented using a 0.18 μm standard cell technology, and the area, throughput and current consumptionwas analyzed. It was concluded that the DSAAM can be implemented with a lower latency than the (S/Ppipe, leading to a higher throughput and lower area and current consumption. Onaverage the area and current consumption of the DSAAM is 50% and 52% lower than for the S/Ppipe, respectively. Furthermore, the throughput of the DSAAM is 37% higher.
