Low Power 8-Bit Square Root Carry Select Adder Constructed By Using 8 Transistor Full Adder
Abstract: Carry select adder is the high speed adder which is designed to speed up arithmetic operations and to reduce the computation time. Carry select adder is used to perform fast arithmetic functions in data processing processors. Low power consumption, reduced area, reduced delay and increased speed are the most important features of the modern electronic system design. In this proposed work, 8 transistor full adder (8T full adder) is used …

Design and Implementation of Carry Select Adder based On Wallace tree Multiplier using Adiabatic Logic
Abstract: The Wallace tree multiplier construction using a carry select adder (CSA) and this paper discusses adiabaticlogic. The proposed design aims to reduce power consumption while maintaining high performance.Adiabatic logic is employed to reduce power dissipation by recycling energy during the logic transitions. TheWallace tree multiplier is used to perform fast multiplication of two large numbers by breaking down themultiplication process into smaller sub-tasks. The CSA is used as the adder …

An Area Delay Optimized Carry-Select Adder
Abstract: In arithmetic and logic unit of digital signal processor (DSP), adder is the important hardware unit. Carry select adder (CSLA) is the best example of the adder used in DSP and it is widely used in many data processors to increase speed. So, the adder performance affects the overall system-performance. The Regular Square root (SQRT) CSLA consists of two Ripple Carry Adders (RCA), so it consumes more area due to …

Implementation of Carry Select Adder with Reduced Area Scheme
Abstract: Addition is the heart of arithmetic unit and the arithmetic unit is often the work horse of a computational circuit. So, adders play a key role in designing an arithmetic unit and also many digital integrated circuits. Carry select adder (CSLA) is one of the fastest adders used in many data processors and in digital circuits to perform arithmetic operations. But CSLA is area-consuming because it consists of dual ripple …

GDI Logic Implementation of Variable Sized CSLA Architectures Using 45 nm SOI Technology
Abstract: Carry select adder (CSLA) is an efficient adder used in modern processors. But, the CMOS logic implementation at the transistor level makes it complex. The use of smaller transistor size has shrunk the overall design but the transistor count was retained. Hence, in this paper the transistor level implementation of variable sized CSLA architecture is done using gate diffusion input (GDI) logic. This implementation drastically simplifies the CSLA in terms …
