Worked on the OpenXiangShan/GEM5 repository to enhance the accuracy and reliability of CPU-O3 pipeline and memory subsystem simulations. Focused on correcting Load Store Queue behavior and refining load replay timing, which improved pipeline progression and data forwarding. Addressed cache and memory hit/miss detection by introducing more precise flag handling and one-cycle miss processing, leading to better modeling of cache behavior. Emphasized code quality through formatting and maintainability improvements. Utilized C++ and applied expertise in CPU architecture, cache coherence, and performance modeling to deliver changes that support more accurate simulation and facilitate future optimization of CPU-O3 workloads.
