Signed digit (SD) number systems support digit-parallel carry-free addition, where the sum digits absorb the possible signed carries in {−1, 0, 1}.

Two new structures for ANY and CONS gates are presented, then a novel half-adder for RBSD numbers which also can subtract the numbers is proposed, ...

Oct 22, 2024 · A highly efficient high radix maximally redundant signed digit adder, based on IE-negabits, has been recently offered [14] . We have previously ...

In this paper a new maximally redundant HRSD adder is proposed. This adder is compared to some most efficient HRSD adders previously published. The proposed ...

The designs of trinary and quaternary signed-digit numbers based adders are presented using different polarized states of light. These proposed polarization- ...

In this paper, we examine three previous nonspeculative MRSD adders and offer an improved design with significant savings in latency, area consumption and power ...

Abstract. Signed digit number systems provide the possibility of constant-time addition, where inter-digit carry propagation is eliminated.

In the new adder, the value of the carry to the next digit can be obtained with a simple logic circuit rather than having to perform an addition and a ...
