Design of Roba Mutiplier Using Booth Signed Multiplier and Brent Kung Adder
Journal Title: International Journal of Engineering and Science Invention - Year 2018, Vol 7, Issue 4
Abstract
Approximate Circuits Are Becoming An Effective Solution To Co Accurately Operating Circuits If Energy Efficiency Is Concerned And The Application Is Error Tolerant. In This Paper An Approximate Multiplier Which Is Based On Rounding Is Designed Using Booth Signed Multiplier And The Brent Kung Adder. The Brent Kung Adder Is One Of The Parallel Prefix Adder Which Greatly Reduces The Consumption Of Area For Higher Order Bits. Booth Sign Multiplier Is Used For Intermediate Multiplication Process Which Greatly Reduces The Delay When Compared To Other Multipliers. This Proposed Approximate Multiplier Has Less Delay And Consumes Less Area And Its Efficiency Is Compared With Those Some Of Previous Approximate And Accurate Multipliers In Terms Of Power, Area And Delay.
