A low power carry select adder with reduced area
A carry-select adder can be implemented by using single ripple carry adder and an add-one circuit [1] instead of using dual ripple-carry adders. This paper proposes a new add-one circuit using the first zero finding circuit and multiplexers to reduce the area and power with no speed penalty. For bit length n = 64, this new carry-select adder requires 38 percent fewer transistors than the dual r...
متن کاملLow power and reduced area Carry Select Adder
Power dissipation is one of the most important design objectives in integrated circuits, after speed. As adders are the most widely used components in such circuits, design of efficient adder is of much concern for researchers.From the structure of the CSLA, it is clear that there is scope for reducing the area and power consumption in the CSLA. This work uses a fewer transistors to significant...
متن کامل128 Bit Low Power and Area Efficient Carry Select Adder
Carry Select Adder (CSLA) which provides one of the fastest adding performance. Traditional CSLA require large area and more power. Recently a new CSLA adder has been proposed which performs fast addition, while maintaining low power consumption and less area. This work mainly focuses on implementing the 128 bit low power and area efficient carry select adder using 0.18 μm CMOS technology. Base...
متن کاملDesign of Area and Power Efficient Modified Carry Select Adder
Adders are one of the widely used digital components in digital integrated circuit design. The Carry Select Adder (CSA) provides a good compromise between cost and performance in carry propagation adder design. However, conventional CSA is still area-consuming due to the dual ripple carry adder (RCA) structure. In this paper, modification is done at gate-level to reduce area and power consumpti...
متن کاملDesign of Low Power Reduced Wallace Multiplier with Compact Carry Select Adder, Half Adder & Full Adder Using Cmos Technology
The Wallace Multiplier is mainly used in the Arithmetic & Logic Unit (ALU) to perform the scientific computation in processors, controller etc... The existing multiplication technique like booth multiplier, array multiplier etc requires more time in multiplications. Hence Wallace Multiplier has been designed by using the parallel process to reduce the delay. The regular Wallace Multiplier requi...
