LP5X-PIM Sim: A High-Fidelity HW/SW Integrated Simulator for LPDDR5X-PIM
This work provides a simulation tool for evaluating LPDDR5X-PIM systems, but it is an incremental improvement over existing simulation frameworks.
Samsung developed a high-fidelity HW/SW integrated simulator for LPDDR5X-PIM, enabling precise evaluation of system performance and energy efficiency while maximizing PIM resource utilization.
This tech note describes the architecture and execution results of the LPDDR5X-PIM simulator, developed by Samsung Electronics. Based on the latest research and internal specifications, the simulator provides a high-fidelity model of both the hardware data paths and the software control layers of the LPDDR5X-PIM block. This integrated hardware-software simulation approach enables precise evaluation of system performance and energy efficiency while maximizing PIM resource utilization. We have refined existing simulation frameworks to align with actual hardware implementation, ensuring consistent behavioral accuracy. Further technical details regarding the specific architecture and circuit design of the LPDDR5X-PIM will be disclosed in future publications
