Abstract: A phase change memory (PCM) based storage system with novel logical device is proposed, and it can off-load compute-intensive tasks from sever to the storage. In such a way, the proposed PCM-based storage system can avoid extra data transfer and improve efficiency of data processing with parallelism capability of logical device. Moreover, PCM promises to increase the overall system performance due to its unique features. Experimental results demonstrate that the proposed system is vastly superior to the traditional way.

Key words: phase change memory (PCM), in-storage processing (ISP), field-programmable gate array (FPGA), sorting algorithm, stream computing
