Zhaohong contributed to the OpenXiangShan/ChiselAIA repository by developing and refining core hardware features focused on AXI4-to-Lite protocol conversion and MSI transaction handling. Over three months, Zhaohong enhanced data-path separation and modularity, introducing robust read/write channel management and parameterized transaction logic to improve correctness and maintainability. Using Chisel, SystemVerilog, and Scala, Zhaohong addressed protocol handshake reliability and optimized state machines for higher throughput and easier verification. The work included targeted refactoring and bug fixes, resulting in clearer code structure and reduced risk of data-path interdependencies, supporting safer SoC integration and laying groundwork for future performance improvements.
