In the recent years,error recovery circuits in optimized data path units are adopted with approximate computing *** this paper the novel multipliers have effective utilization in the newly proposed two different 4:2 approximate compressors that generate Error free Sum(ES)and Error free Carry(EC).Proposed ES and Proposed EC in 4:2 compressors are used for performing Partial Product(PP)*** structural arrangement utilizes Dadda structure based *** to the regularity of PP arrangement Dadda multiplier is chosen for compressor implementation that favors easy standard cell ASIC *** this,the proposed compression idealogy are more effective in the smallest n columns,and the accurate compressor in the remaining most significant *** limits the error in the multiplier output to be not more than 2n for an n X n *** choice among the proposed compressors is decided based on the significance of the sum and carry signals on the multiplier *** an enhancement to the proposed multiplier,we introduce two Area Efficient(AE)variants viz.,Proposed-AE(P-AE),and P-AE with Error Recovery(P-AEER).The proposed basic P-AE,and P-AEER designs exhibit 46.7%,52.9%,and 52.7%PDP reduction respectively when compared to an approximate multiplier of minimal error type and are designed with 90nm ASIC *** proposed design and their performance validation are done by using Cadence *** performance evaluations are carried out using cadence encounter with 90nm ASIC *** proposed-basic P-AEA and P-AEER designs demonstrate 46.7%,52.9%and 52.7%PDP reduction compared to the minimal error approximate *** proposed multiplier is implemented in digital image processing which revealed 0.9810 Structural SIMilarity Index(SSIM),to the least,and less than 3%deviation in ECG signal processing application.
