Received: 14 August 2019 Accepted: 29 Decemebr 2019 Digital Signal Processing (DSP) applications demand error-free and compact hardware architecture of arithmetic operations. A logarithmic operation provides an efficient option in place of binary arithmetic. In this paper, it is suggested that 11-region and 17-region error correction schemes for developing an efficient antilogarithm converter. It is used for developing the most accurate and compact logarithm multiplier which is used in the DSP processor. Implementations of reported and proposed designs are investigate based on accuracy and hardware overhead and it found outperform in comparisons of previously reported designs. The proposed 11region converter involves 61% less Area Delay Product (ADP) and 49.82% less energy in comparisons of the reported 11-region antilogarithmic converter and 17-region converter involves 48.02% less ADP and 32.53% less energy in comparisons of the reported 14-region antilogarithmic converter. The proposed antilogarithmic converter achieves 1.697% and 1.084% error for 11-region and 17-region designs respectively than of reported designs of 1.876% and 1.351% for 11-region and 17region respectively.
