Abstract

In data centers, inline data deduplication which eliminates redundant data on the fly, is crucial to significantly reduce storage cost. However, it causes substantial performance and energy overhead due to a large number of memory accesses in the conventional GPU. In this paper, we propose a highperformance processing-in-memory accelerator for inline data deduplication, called Deduplication Unit (DU) to reduce the latency and power consumption. We place the DUs in a base die or core dies of a 3D stacked memory to improve performance. Our simulation results show that the DUs in the base die reduce the latency and processing unit power consumption by 17.3% and 45.5%, on average, respectively, compared to the conventional GPU. In addition, in our thermal simulation, peak temperature of the DU is still lower than the threshold temperature.
