Design of an Efficient 128-Bit Carry Select Adder Using Bec and Variable csla Techniques
Design of areaand power-efficient highspeed data path logic systems forms the largest areas of research in VLSI system design. In digital adders, the speed of addition is limited by the time required to transmit a carry through the adder. Carry Select Adder (CSLA) is one of the fastest adders used in many data-processing processors to perform fast arithmetic functions. From the structure of the...
متن کاملCarry Select Adder – Review
To perform fast addition operation, CSLA is one of the fastest adders used in many dataprocessing processors. There is further scope of improving the performance parameters of CSLA. This paper provides a comparative analysis of CSLA and reviews about various proposed schemes used to reduce the delay time, area occupied and power consumption in CSLA.
متن کاملLow Power, Area and Delay Efficient Carry Select Adder Using Bec-1 Converter
In performing fast arithmetic functions, Carry select adder (CSLA) is one of used in many data processing processors to perform fast arithmetic functions. Adders are the basic building blocks in digital integrated circuit based designs. Ripple carry adders are slowest adders as every full adder must wait till the carry is generated from previous full adder. CSLA (SQRT CSLA) architecture have be...
متن کاملHigh Speed, Low Power, Area Efficient Mux-Add and Bec Based Implementation of Carry Select Adder
Adder being the basic hardware block of any arithmetic operation, the major constraint in the field of signal processors, data processors to perform any operations are highly dependent on the adder performance of the circuit. The gate level implementation of the carry select adder (CSLA) and modified carry select adder has significantly reduced the area and power consumption which replaced the ...
