PROFILE
Ziyue Zhang
Ziyue Zhang contributed to the OpenXiangShan project by developing enhancements for RISC-V vector and floating-point features across multiple repositories. In XiangShan, Zhang improved vector length state management by eliminating stale destination values and refactoring the busy table to support new read/write ports, which increased the reliability and correctness of vector operations. For NEMU, Zhang implemented MMU-aware half-precision floating-point load and store instructions, ensuring proper memory translation under the RVZFH extension. Additionally, Zhang enabled Zvbb extension support in riscv-isa-sim and updated build dependencies in ready-to-run. The work demonstrated strong skills in CPU architecture, hardware design, and C programming.

Nov 1, 2024Concise monthly summary for 2024-11 focused on OpenXiangShan/XiangShan: Delivered a Vector Length State Management Enhancement that eliminates stale vector destination (vd) values when reading vector length (vl) state and refactors the busy table to support new read/write ports for vector length information. This improves correctness and performance of vector operations, reduces stale data risks, and strengthens the vector path reliability.
