Abstract: In this paper, we present a new digit-serial hybrid adder. The adder can be pipelined to the bit-level and is, therefore, well suited for high-speed applications. The main advantage of the ...

Basically in digital system there are two type of circuit: combinational logic circuit and sequential logic circuit. When the authors talk about combinational circuit, this circuit is that circuit of ...

Abstract: An improved 32-bit carry-lookahead adder (CLA) with conditional carry-selection (CSS) is proposed in this paper. The new adder is compared with serial adder and pure carry-lookahead adder.
