Abstract
The RFET-based approximate adders lead to reduced power, area, and delay while having a minimal impact on the accuracy of the DNN/CNN. In addition, we carry out a detailed study of varied combinations of architectures involving CMOS, RFETs, accurate adders, and approximate adders to demonstrate the benefits of the pro- posed RFET-based approximation. The proposed RFET-based accelerator achieves an accuracy of 94% on MNIST datasets with 93% and 73%reduction in the area, power and delay metrics respectively compared to the state-of-the-art hardware accelerator architectures.
