In present years, integration technology is drastically changed and urgently needs the high-speed adder circuits for the image processing (IP) applications (APL) like image smoothing (IS) and image sharpening (ISH), but unfortunately any exact adder circuit did not use IS and ISH, so few researchers proposed approximate adders (AA) for IP APL and also improved the speed compare to exact adder circuits (CKT), and still there is no systematic literature survey about AA. This paper gives the one root map for AA, and this is more useful for some of the researcher’s work in this area. Finally, the performance analysis of AA in terms of power consumption, delay, area, PDPm, and error is provided.
