PROFILE
Xuan Hu
Over a three-month period, contributed to the OpenXiangShan/XiangShan repository by enhancing memory operation type handling, vector processing, and backend architecture. Applied Scala and Chisel to refactor the LSUOpType system, introducing enumerations and safer construction pathways for memory operations. Improved reliability and maintainability by stabilizing writeback bundle connections and overhauling vector length handling, including the allocation and wiring of VTypeBuffer entries. Addressed backend immediate value handling by migrating to a case class structure, increasing type safety. The work focused on improving code clarity, reducing runtime risk, and laying a foundation for scalable hardware-software integration and future performance optimizations.

Nov 1, 2025Month: 2025-11 — Focused on strengthening memory operation type handling in OpenXiangShan/XiangShan through a targeted refactor of the LSUOpType system. Delivered a feature that adds a robust OpType construction and opcode retrieval pathway, along with enumerations for sizes (B, H, W, D, Q) to improve readability and maintainability. This work lays the groundwork for safer, more scalable memory operation generation and reduces future debugging effort.
