Performance Analysis of High Speed Adders
A. Surya · International Journal for Research in Applied Science and Engineering Technology · 2019
Adders are one of the most widely digital components in the digital integrated circuit design.In any arithmetic function addition plays a role of most fundamental operation.Adders are commonly used in miscellaneous application in modern VLSI system like multiplier design, design of an ALU, and also in various Digital Signal Processing algorithms like FIR, IIR Filter design.Designing an excellent and efficient of an adder circuit a designer must optimize the parameters like area, delay, and power.We have to tradeoff between all three parameters to get an efficient design.Depending upon the need and application some changes and compromises have to be made In this paper, the design of various adders such as Ripple Carry Adder, Carry Skip Adder, Carry Increment Adder, Carry Look Ahead Adder, Carry Save Adder, Carry Select Adder, Carry Bypass Adder are discussed and are compared on the basis of their performance parameters such as area, delay and power distribution.
