Low-Power Ternary Multiplication using Approximate Computing

Project Code :TVMABE131

Abstract

In this paper, a novel approximate computing technique for low-power ternary multiplication is proposed. A carry-truncated ternary multiplier, error compensation circuits and 2×2 ternary multipliers with various accuracies are proposed using the low-power design methodology with Carbon NanoTube FETs (CNTFET). An accuracy-configurable design method is proposed to design energy-efficient 6×6 approximate ternary multipliers. The energy benefit of the proposed 6×6 approximate ternary multipliers has been verified using HSPICE simulation. The proposed approximate design improvement in PDP and accuracy over the previous approximate multiplier-based design.
