Xiaoyu Cao enhanced the memory subsystem in the OpenXiangShan/GEM5 repository by implementing per-cycle single-entry MSHR arbitration and introducing configurable allocation limits to cache structures. Using C++ and leveraging expertise in CPU architecture and memory system design, Xiaoyu addressed performance bottlenecks by restricting MSHR allocations to one per cycle and improving the handling of alias failures and write buffer hits. This targeted feature improved the fidelity of memory performance modeling and reduced system stalls, supporting more accurate hardware-software co-design analysis. The work demonstrated a focused, in-depth approach to performance optimization within a complex simulation environment over the course of one month.
