Title: LP5X-PIM Sim: A High-Fidelity HW/SW Integrated Simulator for LPDDR5X-PIM

Abstract:

This technical note outlines the architecture and execution outcomes of the LPDDR5X-PIM simulator, a tool created by Samsung Electronics. Grounded in current research findings and proprietary specifications, the simulator delivers a highly accurate representation of both the software control mechanisms and hardware data pathways within the LPDDR5X-PIM module. By adopting a unified hardware-software simulation methodology, the tool facilitates the exact assessment of energy efficiency and system performance, while simultaneously optimizing the utilization of PIM resources. The team has enhanced established simulation frameworks to mirror real-world hardware implementations, thereby guaranteeing precise behavioral fidelity. Additional insights into the circuit design and specific architectural details of the LPDDR5X-PIM will be revealed in forthcoming publications.
