The paper introduces AdAM, an innovative adaptive fault-tolerant approximate multiplier designed for ASIC-based DNN accelerators. By employing an unconventional use of the leading one position value of inputs, the proposed architecture optimizes resources and enhances reliability. Through lightweight fault mitigation techniques, faulty bits are set to zero, resulting in improved reliability metrics compared to traditional methods like triple modular redundancy (TMR). The study showcases a significant reduction in area usage by 63.54% and a lower power-delay product by 39.06% when compared to exact multipliers. The research aims to strike a balance between power efficiency and vulnerability while maintaining high reliability levels.
