In this paper carry select adder using prefix adders i.e., by replacing Ripple Carry Adder (RCA) with Cin = 0 with Kogge Stone Adder (KSA) is implemented to reduce delay between intermediate stages with increase in area. At gate level, the KSA is modified to reduce the area of the ...
adders are most important and essential block of these system, design and selection of adders plays a very important role, this paper presents a comparative study of five different adders like Ripple Carry Adder, Carry Skip Adder, Carry Lookahead Adder, Kogge Stone Adder, with performance metrics...
The proposed gate is used to design ripple carry adder, BCD adder and the carry look-ahead adder. The most significant aspect of the proposed gate is that it can work singly as a reversible full adder i.e reversible full adder can now be implemented with a single gate o...
Area efficient implementation of ripple carry adder using memristor crossbar arrays. In Proceedings of the 2016 11th International Design & Test Symposium (IDT) IEEE, Hammamet, Tunisia, 18–20 December 2016. [Google Scholar] Lin, C.; Zhong, H.; Wang, X.; Zeng, Z. Several Logic Gates ...
For example, the "straightforward" method of a ripple carry adder produces a circuit that is extremely small in size, but with a depth of O(n), where n is the number of digits in the input binary numbers. Carry look-ahead adder, carry bypass adder, and carry select adder circuits ...
3.2. Fundamental concepts of the evaluation method In order to carry out the evaluation of a given function Ψ we propose to approximate it through a discrete function F defined as follows: F0 ∈ R, Fi+1 = Fi ⊕ Gi, ∀i, i ∈ N, Fi ∈ R, Gi ∈ R. (9) The first value of ...
The if-then adder was proposed in another work where it shows an efficient performance when compared with the well known ripple carry adder (RCA) and the carry lookahead adder (CLA). The online DALUT with the if-then adder was applied in designing 70-tap finite impulse response pulse ...
The proposed gate is then used to design reversible ripple carry and carry skip adders. It is demonstrated that the adder architectures designed using the proposed gate are much better and optimized, compared to their existing counterparts in literature; in terms of number of reversible gates and ...
Ripple carry adderPower dissipationNew dynamically Controllable DC voltage Level Converter (DCLC) technique has been developed for use in high-speed, low-power circuits. The level converter can increase the DC voltage which is supplied to a active-load circuit on request, or supply a minimal DC ...
The proposed gate is used to design ripple carry adder, BCD adder and the carry look-ahead adder. The most significant aspect of the proposed gate is that it can work singly as a reversible full adder i.e reversible full adder can now be implemented with a single gate only. It is ...
