Publication number: 20220318628Abstract: Hardware noise-aware training for improving accuracy of in-memory computing (IMC)-based deep neural network (DNN) hardware is provided. DNNs have been very successful in large-scale recognition tasks, but they exhibit large computation and memory requirements. To address the memory bottleneck of digital DNN hardware accelerators, IMC designs have been presented to perform analog DNN computations inside the memory. Recent IMC designs have demonstrated high energy-efficiency, but this is achieved by trading off the noise margin, which can degrade the DNN inference accuracy. The present disclosure proposes hardware noise-aware DNN training to largely improve the DNN inference accuracy of IMC hardware. During DNN training, embodiments perform noise injection at the partial sum level, which matches with the crossbar structure of IMC hardware, and the injected noise data is directly based on measurements of actual IMC prototype chips.Type: ApplicationFiled: April 6, 2022Publication date: October 6, 2022Applicant: Arizona Board of Regents on behalf of Arizona State UniversityInventors: Sai Kiran Cherupally, Jian Meng, Shihui Yin, Deliang Fan, Jae?sun Seo
