LUTIC: A CRAM-based Architecture for Power Failure Resilient In-Memory Computing

Abstract

Processing In-Memory (PIM) based on emerging non-volatile memory technologies can accelerate machine learning tasks even for batteryless devices operating intermittently. However, existing PIM solutions for intermittent systems offer limited parallelism and do not support a high degree of programmability. This paper presents LUTIC —a novel architecture that can accelerate a broader class of intermittent data-intense operations. Our results demonstrate that, compared to existing commercial low-energy accelerators and PIM solutions for intermittent computing, LUTIC improves performance and energy efficiency with better parallelism support.
