Abstract
The cost of transferring data between the off-chip memory system and compute unit is the fundamental energy and performance bottleneck in modern computing systems. Furthermore, with the advent of emerging data-intensive applications and technology scaling, this bottleneck has continuously increased. To overcome these difficulties, Near Memory Processing (NMP) based on 3D die stacking becomes a potential technology to transform the <italic xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">computation-centric</i> system towards <italic xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">memory-centric</i> system. In this work, we explore the feasibility and efficacy of a NMP architecture based on an emerging Non-Volatile Memory technology (NVM) for data-intensive applications and compare it with the conventional 3D-stacked NMP architecture based on DRAM. We demonstrate the effectiveness of our approach with experimental results.
