Contributed to the OpenXiangShan/XiangShan repository by delivering two core features focused on memory subsystem performance and reliability. Developed memory prefetching enhancements for L1 and L2 caches, improving timing by registering address outputs and resolving multi-level prefetch timing issues. Modernized the StoreUnit with a multi-stage pipeline, new variants, and improved handling for unaligned and vector stores, as well as TLB miss scenarios. Addressed reliability and correctness by fixing allocation and address handling bugs within memory queues and cross-store operations. All work was implemented in Scala and Chisel, emphasizing backend development, hardware design, and maintainable memory architecture improvements.
